Just tried CS 767 with UT2 traffic on i7920 @ 3.7Ghz

Recommended Posts

Guest JamesWoods

Captain Sim 767 is about as frame rate hungry as pmdg 747, or maybe even just a bit more.But my real problem is the crapy frame rates and massive stutters i get with UT2 traffic injection. Not normally a problem, unless you approaching a busy airport, then the landing becomes a slide show.Think its time for me to go back to TrafficX, UT2 traffic injection is turning my landings at busy airports into a slide show.And i got only 38% commercial traffic / 25% GA. But Still Heathrow airport proved too much for it, my frames were down to 10~9 from locked 30 in cruise.Then i tired landing again from saved flight with UT2 tuned off, and i got a reminder of how smooth FSX used to be before i got into the mess of UT2 traffic injection stutters.When i asked Ut2 support about when a fix coming for Ut2 traffic injection bug, could not get response, they just siad they gona produce a fix, but not when.Even though the AI looks much better in UT2, am still going back to trafficX , i have had enough of UT2 traffic injection stutters.After a few months of UT2, ill say the only good thing about it is the Ai models , After that everything else just makes FSX sluggish Now where did i put that TrafficX license again..................................................................................

What "traffic injection bug" are you speaking about?UT2 runs smoothly and flawless for most of the users.Just make a search and you'll see that almost everyone here enjoy this addon.

I agree with James a little about the UT2 injection. Sometimes its really bad. For what ever reason I seem to be getting more injection pauses now than I did when I first installed UT2. Sometimes I stop traffic completely from the pulldown menue and justy go AI less for the rest of the flight. It's been so many years since I have not flow with AI that I forgot how nice it is just be be alone with no AI running you down on final. It's also amazing how much more performance you get in large hub with no AI.However, I still think that UT2 is still the best AI program I have ever used and has a lot of potential once they get all the little things like that ironed out.

The makers of UT2 are aware of , and admit to the problem of which i speak, below is a quote from thier forum from one of thier support guys.----------------------------------------------------------------------------------------------------------------In the upcoming service pack, we are going to expose several parameters which will give you control over the traffic injection rate and interval. Hopefully this will minimize or eliminate the problem for you. How much traffic injection pause you experience will depend on the specs for your PC. The initial pause when the session begins will probably not change much. Regards And A link to the thread on UT2 customer forum. Just in case you feel like a read.http://ultimatetraffic.flight1.net/forums/forum_posts.asp?TID=6251----------------------------------------------------------------------------------------------------------------And if that is not enough i can find you more threads like that here on Avsim, I mean threads from users of the product, not covert promoters of the product.We got a world reccesion going here David, sellers want to sell maximum products, and we buyers looking maximum value, its a conlict of interests.And as long as we have the right to voice our opinion in order to warn or advice others, then each shall freely give his opnion until silenced AGAIN.So David, as you can see from the UT2 forum link i put above, even UT2 support admit to having the problem you say they dont have.Dont get me wroung its a nice product, but heavy stutters on approach to big airports makes it almost unsable for me, thier dynamic traffic injection technology which is not used by any other FSX AI traffic developer is causing major down to 1FPS stutters at busy airports, EVEN WITH LOW TRAFFIC SETTING LIKE 30% commercial traffci on a very fast PC..Other than this major issue, there is no other product that can compete with UT2, but with this problem, i am about to reinstall my TrafficX until they fix the BUG.

There are two major problems with UT2, if they can be fixed, the product has no competition for miles1 - Stutters of down to 1FPS from 17 FPS during approach. Its A Slide Show landing at Big Airports2 - Traffic gets reset when you go to FSx menuThese are issues that no other traffic program has got, but UT2 has the best models by faaaaar i do agree.But the very nice UT2 models dont make up for the slide show approach i get at busy airportsEven at 30% commercial traffic its a slide show on i7920@3.7GHZ with nvidia gtx 285.personally i am removing UT2 from my system and going back to TrafficX till they fix the problem. TrafficX models are not nearly as good as UT2, but then i dont fly in AI cockpit, i fly in my VC, which with UT2 is stuttering too much due to dynamic traffic injection technology that is not working.

You mentioned you were flying the CS767 - do you get the same problems when you fly other aircraft?I don't have these problems with UT2. I can understand David's surprise, since I had also never heard of this before either. However, I am aware that UT2 has it's fair share of bugs, and reading through the forums tells me that some people experience them, and some people don't. The one bug I have personally experienced is the one where if I start in a helicopter, I don't see any AI traffic. For some reason, if I start in a regular aircraft, and switch to a helicopter, then I do see the AI traffic. From reading the boards, it seems that some people have experienced this, but most haven't.I wonder if this is related to your settings at all? Just a thought. I run my i7-920 @ 3.6GHz, but I tend to be conservative with my settings in order to keep the framerate high. I know most overclockers really like the sliders to the far right, so you might try bringing them back a little. Of course, I still notice a hit from AI aircraft, but it definitely doesn't turn into a slide show. I'm not saying that this is causing it, but it might be interesting to check. I realize that when dealing with systems like your, you may not want to compromise on the settings, but that is what FSX is all about - compromise.Anyway, besides the helicopter bug, I haven't had any problems. I hope they get all this fixed one day, but I'm still happy with the product.- Martin

HiWhen i first installed UT2 i did not like the pause due to traffic injection, but as cmpbells mentioned its seems to have gotten worse recently, maybe its something to do with the patch.I prefer to have a smooth flight, so i am also conservative with the sliders, and other than at busy airports fsx and UT2 are fine.But even at a conservative setting of 30% commercial traffic, i get down to 1fps pauses on approach, then it jumps right back to 17fps. The product is no longer really usable on my system.Obviouslly the only reason that UT2 producers will even go as far as to say they are working on a fix for traffic injection means its not just me and my brother that have the issue.All we trying to find out from UT2 is when they plan to release this fix so that UT2 can be used at big airports.CS767 is an unusually frame rate hungary aircraft, but the UT2 issue i have with every A/c, CS767 just makes the problem much more pronounced.Its not a flightSim if you pausing down to 1fps when UT2 injects traffic ever so often during approach. The only advantage of Ut2 traffic injection that i can see is is that the landing are so much easier, cause you have lots of time to line up at 1fps.

I have noticed alot of stuttering at big airports no matter what aircraft i fly w/ UT2 lately. I have traffic X also so let us know how you frames look w/ Traffic X installed instead of UT2.

Thanks for the link James.3 remarks:- Mr "Jaksanfactor" has been banned from Avsim's forums for being rude and not civilized. The way he express his opinion is not for me the best way to be understood.- When Tom Murdock answers "Hopefully this will minimize or eliminate the problem for you" I don't think he speaks to all the users but only to those having a pause problem with the traffic injection. Even without traffic addon, Heathrow is with Amsterdam, Paris and Barcelona the biggest hubs in Europe and FSX engine doesn't like hubs! Obviously every traffic addon will simulate more or less the intensity of these airports and even at 4.5 Ghz you will notice stutters.- I haven't pay attention to a change after the latest update but I probably missed it, I actually only virtual fly in Tongass Fjords! :--) I will give a try in heavy airports, maybe there is a problem I was not aware of but anyway I think that even if you have a high end computer every traffic addon will slow down frames (I've tried them all).Now, when you say "We got a world reccesion going here David, sellers want to sell maximum products, and we buyers looking maximum value, its a conlict of interests. And as long as we have the right to voice our opinion in order to warn or advice others, then each shall freely give his opnion until silenced AGAIN.", I can assure you that no one here will take you the right to voice your opinion as far as you comply with the forums rules! :--)

This is really interesting to read. I fly FS9. I did originally switch over to FSX but I reverted back to FS9 because I couldn't fly at major airports with scenery and 100% ai which is a big deal for me. My 5 year old system handles the major hubs just fine in FS9 - not perfect but well enough.Anyway, I have been looking at building a I7 rig for FSX with the hope of being able to fly the way I like it - sliders to the right, full ai and lots of add on scenery. I have also considered buying UT2 but I would be fine using the traffic I already have - some old UT stuff with a menagerie of WofAI and other freeware.What I'm trying to figure out from this thread isIs UT2 the problem or is FSX still unable to produce good results in these situations with the hardware currently available?If I can't run full ai at major airports in FSX it would be a complete waste of money to build a new rig at this point. I would be back to FS9 in a heartbeat.

There are numerous threads in the hardware section proclaiming the virtues of an overclocked i7-920. I recently made the upgrade from my trusty Q6600, and I have been very happy. The OP was talking about a specific problem with UT2 which was exasperated when he was running the CS 767.Check out the hardware section, or do a search for "i7" or "920". There are many happy upgraders in here - don't let this one topic discourage you.- Martin

UT2 is fully the problem in this case, My system is i7920@3.7Ghz. Nvidia GTX285This PC runs FSX like FSX is as light as a feather, everything is smooth and sailing.But no matter how powerfull your PC when you have a addon with fundamentally Buggy code, not even the most powerfull PC in the world can help.IMHO, dont get UT2 till they have fixed this issue of traffic injection causing the sim to pause.TrafficX is a good trafic program, models are not as good as UT2, but atleast you wount get slow motion landing at busy airports.To answer your question, i7920 with OC up 3.6 GHZ runs FSX, like FSX is a baby, even if you push many sliders way up.But not all.I think the problem we having is this continous stream of buggy addon releases for FSX, causing peoples systems to perform less than acceptable.Get yourself a nice i7, and dont install any addon on your system till its been out a while, and you have read the forums.Cause it seems fsx addon producers are releasing very buggy stuff this days.Also i have to exercise caution and say that, some of the newer addons are also pushing the limits of what the CPU can drive, like rex HD textures for example. I sacrifice some Fps for better looking clouds.If you planning on using heavy commercial traffic stay well clear of UT2 for now, the traffic injection pauses do ruin a good flight.When its fixed, along with the traffic being reset when you access menu, then UT2 is the thing to get, cuase its generally FPS friendly until........................traffic gets updated ...then its smooth..... Basically everyhting stops, including your plane when traffic gets updated, otherwise its smooth.Get yourself a really good cpu cooler, cause the more you OC the more FPS you get in FSx, and turn HT off. With HT off you can OC more.If i remove all addons and just run defualt FSX, i can put all sliders to the right and then some. So its the addons that are giving the i7 cpu somne challenge.Some addons are worth the fps hit they give like rex , pMdg, but others are a hiy on fps cause they badly written software, like UT2.You dont need to be genious to know that a flight simulator only works when things move smoothly continously, unlike in a shooting game where stutters are not so noticable. So its suprising that UT2 will adopt a strategy of waiting till you are about to land before bombarding the cpu with traffic work load that makes your landing look like some 18th century slide show. So even with i7 975 youll still have to choose your addons carefully .And the newer addons are more demanding on the cpu. While others are just dan right buggy.1 - UT2 ---------------Moiving to trafficX2 - REX2 -------------moved back to rex13 - CS767 ---------------this has a bug where its bombarding FSX with a thousand useless messages a second, check fsuipc logging to see the messages. So its not fps friendly at all cause half your cpu is wasted processing buggy messages from the cs767. To name a few that have had me doing reinstalls recently. Some of the better more stable FSX products that make it fun to sim.1 - ASA2 - RC4These dont leave you reaching for your fsx cd to do a fresh install.

I'm not sure what traffic injection issue you have but the only injection I see is the one when ut2 first starts and your pc pauses for about 3-5 seconds while the traffic loads. Once that happens then there is no further injections that I see. The frame rate issues you have are just due to the nature of the cpu hungry AI code inherent with FSX. UT2 has lots of other bugs for me like when stopping traffic my frame rate does not improve which means the sim is still processing AI even though it is not on screen anymore. The reload of traffic after accessing the menu is also unacceptable. There are also some strange behavior with the aircraft themselves rolling around in the grass and coming in for landings and going around constantly. The program has potential for sure but they have MAD bugs to work out of it first and I don't like being their beta tester on my dime. I keep thinking about going back to trafficx which I purchased about 2 weeks before UT2 came out but overall with this new pc even with most settings to the right and 60% heavies and 75% GA in UT2 I still get 20-30fps at most hub airports loaded with traffic. FSDT's O'hare has about 50+ heavies and 15 or so private jets and I can pull anywhere from 18-40fps with the steady average being around 24fps. It's nice :)

you running @4GHzAnd i can say that ut2 used to be better on my system sometime ago but not recently.think i might remove ut2 and try it without the recent patch. do you have the patchdo you have rex2 installed.maybe those of us who get slide show at busy hubs using rex2 have something in common.But even before the ut2 patch and rex2, i used to get the injection pauses.unfortunatly i cant get my system to run @ 4Ghz

Depends on your cpu. I have lots of headroom still left in this one. I think 4.2 is probably doable pretty easily but I am content at 4ghz. I have a D0 stepping cpu and apparently a pretty good one at that. Requires only 1.27v at 4ghz. The system I tweaked for my dad I could only get to 3.75ghz and barely at that because his temps were much higher than I would like under heavy load but still within spec. The Megahalem cooler I use really is amazing though and imo is 'fairly' comparable to a water setup. I am running the latest patch and no rex2. I use graphicsx because the rex guy would never respond to my question about the comparison between the 2 products so I stayed with graphicsx which has served me well for 2 years. What do these injections do for you? Are you sure it's not just cpu lag from so many heavies being in the same area? Once ut2 injects traffic then it is there afaik. It doesn't keep injecting traffic. I hover over airports all the time in my dodo 206 and once the traffic is there then there isn't any new traffic that pops up out of the blue. At that point then the only change in traffic is from the normal arriving and departing AI.

You probably dont notice the effect cause your system is so powerfull.But according to UT2 producers, when you approach an airport, the traffic at the airport is not loaded until you are close, like in approach phase of your flight.So it waits till you near before it starts loading traffic at that airport, this is when i getpauses down to 1fps, but once its loaded its fine , good fps, until the next pause.The way UT2 traffic injection works is unlike any otther traffic program, cause it does not process traffic what you cant see, until you are close to the area. The problem is you get good smooth flight when far from your landing airport, but as soon as you close to your airport, ut2 starts to process all its back log traffic all at the same time.Its like putting off your laundary till christmas sort of thing. But then it takes you till new year to sort it all out. So on my system all is smooth till am about to land, then i get these pauses that are sharp and heavy down to 1fps. CAuse the cpu is busy processing ut2 traffic its been putting off till i reached the area.They have suggested giving a patch that will allow us to set the rate at which this traffic is injected, but no time scales given.For me i will use TRafficX till they sort it out.

Those ut2 guys will say anything I am convinced. I think they have bitten off more than they are capable of. I can fly from O' hare to Chicago city proper which is 15ish miles away and the second I look back to the O'hare area my frame rate goes from 60 to 24 so I know the traffic is still there. Try it yourself. Fly 10 miles away from a major airport and then look back at the airport and your frame rate will be cut in half. I don't know why ut2 is spreading their BS when they claim that when it is obviously not true. Once traffic is injected then it is injected and is there to stay. If it wasn't then why is there still radio communications with an airport from the AI? I'm guessing they told you that for the same reason they told me that once AI traffic is stopped through the menu then there is no more cpu cycles being taken up. I know that's not true because my frame rate is still the same when I stop the traffic. The frame rate should double for me instantly after stopping ut2 but it does not. And my system is not that much powerful than yours. I get 30fps sitting on the runway at seattle with traffic enabled when I run at 3.7ghz. At 4ghz I get 32. Not much of a difference between us there. Less than 8% and with fsx being so slow already, 8% means nothing. My double ut2 AI settings compared to yours also more than makes up for any performance increase my box may have over yours.

My situation with UT2 has been this.I first bought it the day it came out. Spent about 1/2 hour mipping all the textures and about another 1.5 hours reassigning missing paints from my WOAI inventory. After that it was pretty smooth sailing. Then the first patch came out that fixed the problem viewing the schedule PDF that was due to some font error. Everything seemed to still be working quite well. I would get about a 20 to 30 second pause while the first traffic load commenced then I would only get a short 3 to 5 second pause every once in a while when I would get near a large airport.Now, I haven't updated to the latest patch which I think is version 1.08, but it seems that I have been getting the pauses a lot more frequently lately and they also seem to be longer pauses. Before the pause would be 3 to 5 seconds, now the pauses are more like 10 to 15 seconds. The funny thing is that I am running 100% airline and 15% GA. I recently backed it down to 75% airline and 0% GA but the pauses are still long and frequent.I have no idea what has been causing this as I haven't made any changes to hardware or setup. The one interesting note is that large AI precentages do not cause much of a difference for me FPS wise, even at large hubs, but the pauses when on final are getting to be annoying. What I have done to help, is about 10 miles out from my destination is go ahead and hit the kill traffic button. Then I can make a niice smooth approach and not have to worry about the pause.I believe the pause is just because of the time it takes to load all the needed trafic back off the hard drive. If I had one of those 10,000 RPM hard drives it probably would be pretty quick. I can see my HD light flicker like mad when the sim pauses to load traffic. Maybe they should write a new routine that will load the traffic more gradually rather than loading such big chuncks at once. Then the pauses might either go away or maybe non existant. The thing I can't understand though is how my pauses have gotten worse over the past few weeks.

Interesting. I never really thought about having to inject the traffic. I thought it was already there everywhere, just not visible from far away. So that begs the question. Is it "creating" the traffic when you get nearby or is it just that all that traffic comes into view and bogs your video? If it the first one, then why don't they just do the injection when you are still 30-50 miles out. A circle of say 40 miles where the periphery get filled as you head towards it and gets vacated as you head away? Is it really complicated or just being made that way. I'm dense. I don't get it.Thaellar

Because you would be getting 5-10 FPS if you were lucky if they did that. The UT2 models look very nice but they are far from being true optimised FSX models, most of them are FS9 models have been run through a converter to run in FSX, hence the poor frame rate and the need to keep the reality bubble far smaller than with MyTrafficX for example, which can have about 3 times as many aircraft in the reality bubble (if you use the dx10 schedules which makes sure the older FS9 models aren't used) for the same frame rate hit.

You might have some success by using one of these AfinityMask settings. I use 15.In the FSX.cfg add the following if it is not already there[JOBSCHEDULER]AffinityMask=3use these settings for N as you test and you must EXIT the sim and relaunch between changes255 - all 8 in use254 - 7 in use with the first remaining free252 - 6 in use with the first entire CORE remaining free127 - 7 in use with the last remaining free 63 - 6 in use with the last entire CORE remaining free 1 = 1 core 0001 3 = 2 cores 0011 7 = 3 cores 011112 = 2 cores last 110014 = 3 cores last 111015 = 4 cores 1111

UT2 injects traffic when you are 10 miles out and will not draw AI on the ground at airports if you are over one zero thousand feet. All you that think you can set your AI level at a certain percentage and keep it there all the time are way wrong. 100% AI at KSEA is like 10% at KORD or KATL (try it) We all need to be more realistic with the AI volume settings and adjust for the area. I agree that UT2 still needs some smoothing out in a few areas but I really think the issue is all the calculating that is needed to run a high amount of AI at large airports not to mention the added ground vehicles and the scenery itself usually is more complex than at a smaller hub. Try this and see if it helps you in bigger hubs:1) find a airport of your choice that you can fly into with what you consider to be with good results with you AI at 80% (KSEA, KFLL, CYVR, KTPA) what ever works for you. After finding the airport that gives good results at 80% go into the UT2 interface in my example I am using CYVR. In UT2 place your mouse over the bar that shows the maxium amount of departures. See screen shotsettingut1.jpgNow look at my destination KATL with 80% AIkatlsetting2.jpgTo prove my point with this go ahead and fly the approach to your high volume area of choice at 80% AI Most likely it will not be a enjoyable experience.Now lets tune UT2 for you high volume hub. Go back to UT2 and select your problem hub I am using KATL. Turn down the AI untill you show at the highest point no more than what the highest was at the hub where you had good results at 80% (my example was CYVR)katlsetting3.jpgI had to adjust my AI to 35% to get the traffic down to equal the amount of 80% AI at CYVR. So for that flight I would use a setting of 35% or lower for best performance. Try setting things that way and see if it helps overall.

The UT2 models look very nice but they are far from being true optimised FSX models, most of them are FS9 models have been run through a converter to run in FSX, hence the poor frame rate and the need to keep the reality bubble far smaller than with MyTrafficX for example, which can have about 3 times as many aircraft in the reality bubble (if you use the dx10 schedules which makes sure the older FS9 models aren't used) for the same frame rate hit.
Andy,You are so right. My dream is to use ALL of the MyTrafficX models and use them with the schedules/injection/real FPs from UT2. I know that some MyTrafficX models are being used with UT2, but some very low performing FS9 models are also being used. I am always a hair away from just going back to MyTrafficX over this.
