Sounds like your system needs some tweaking. I am running an I7920 at 3.8 and I have UTX UT2 REX 2.0 GEX and all the fancy add on aircrafts you can shake a stick at and I get frames in the 20s when in new york or so but mainly in the 40 to 70 even with UT2

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.

My frames are locked at 30, and i get more like 15 near ground at busy airports, but with ut2 iget pauses that go down to 1fps for few seconds. Its the pauses that are the problem.if you dont get them with ut2 then lucky you.my system is well tweaked and performnce excellent bar UT2 issues .Ut2 know about this problem and say they working on fix, so i will not be tweaking my system, i just use trafficx till ut2 give us fix.If you got time please try egll with commercial traffic of above 35% and GA about 25%. with this i get pauses that fully stop the plane down to 1fps, then it jumps right back to my normal 17fps.

Another thing you might look at is mipmapping the planes, I know it not only makes mine look better, but also better performance. Don't ask me how, a friend does them for me :(

You guys do have your jetways turned off on UT2?

No, i got jetways on, i dont think jetway off will really improve the shocks i get when ut2 is injecting traffic.But am open to suggestions cause i would rather not have to uninstall ut2 as i am planing to.

It looks like it is not a FPS issues where reducing settings will make a difference. It sounds like the actual loading of the ai is causing the problems. I have always (with a few different systems) had problems with Active Sky loading weather - very similar pauses and then a return to normal fps once everything is loaded. To me it sounds like not only is the pause annoying, the timing of it is bad as well. I could never get to the bottom of why I have pauses with Active Sky. Some people have them and some don't. I even tweaked a previous system with FSGS a few years back and nothing helped. I have had the problem with every Active Sky version for the past several years. I have learned to live with it but I couldn't live with those pauses on approach. Does anyone think it could have something to do with using an on board Raid controller or on board Ethernet or something similar? Do any of you that get these pauses use Active Sky products? If so, any pauses with you weather?Maybe the two issues are completely unrelated. I don't know but it is worth throwing out there. I can't think of any other program that loads a ton of information during flight.

Regararding the effects of addons on fsx smoothness.I get surtle pauses from ASA, but rarely ever noticeable, maybe in some heavy weather situation. I have also set ASA to update weather less often, i think 20mins i set i to.UT2 and ASA task i have set to run only on core 3 while FSX uses cores 0,1,2. This is also in an effort to reduce the effect of high cpu demand from addons on fsx smoothness.I also have Ai smooth running, this also is fixed to run on core 3 only. Set permanently using tool called setaffinity.I usually have excell open with flight plan data, and its also set to permanently run on core3 only.So that any high cpu demand from any task other fsx is seen only on core3, while fsx runs on cores 0,1,2.The ut2services.exe executable is also permanently set to run only on core3. But i still get BIg Time pauses from UT2 on apporoach in busy areas. I have to say that in less busy areas UT2 effect is not so bad.I dont use fpslimiter, as i find running fsx on first three cores only is smoother than fpslimiter on my system. So any addons i just fix to run on core3 only.

Ok, this is interesting - and excuse me for getting off topic.How exactly do you adjust which core you have applications running on? I read the previous post about the AffinityMask setting, but how do you tell Excel that you want it to run on core3? I guess that I always assumed that an application had to be designed to use more than one core, but reading this opens my mind bit.- Martin

If its fsx you want to set to run which cores ---------- use the affinitymask setting in your fsx.cfgIf its a windows user program application ----- you can use taskmaneger to set affinity -- but i use a tool called SetAffinity cause the setting is retianed even after reboot, unlike using taskmaneger where the setting lasts only until the application is shutdown.To make the setting permannent until you decide to chnage it i use SetAffinity . A link to this tool was posted in some topic here recently, so search avsim fsx topics for the link, just type setaffinity in your search.

I would kill to have my planes mipmapped. Same for aerosofts manhattan and sanfran scenery. How do you guys do that and why do devs release garbage like this that isn't mipmapped? I hate this shimmering...

The reason for the "garbage" as you so eloquently put it, is historical. Back in the days of FS9 graphic card just couldn't handle mipmaps. It's a shame AI creators haven't kept up. I too have asked for my money back for UT2. Far too many bugs and misrepresentations. Apart from the AIA and Fruit Stand models in the package, the minor models like props are just atrocious. Any criticism in that direction was swept under the rug in the Flight1 forum. Not my kind of developer. Back to hand mip-mapped, hand-converted, self-installed AI traffic for me ;) Can't beat the quality of DIY.

you guys make me laugh...If your FSX is set up properly you WILL NOT see a performance hit with AI traffic.I run 70% commercial and 30% GA and see no performance hit at all, in fact performance is better than with default AI planes.I run UT2 and have not had any problems at all with it, so quit complaining about it not working properly.I used to use WOAI, which is excellent but I now use UT2 as it is a lot less work.Once you've got your AI planes mipmapped, UT2 looks great.

There is absolutely no denying that UT2 has a significant impact on frame rates anyone that says otherwise is not being totally honest or has some other motive in mind, whether this impact is significant enough on the users system to cause unaceptable performance is purely a matter of taste, some people may be able to put up with frame rates below 25 in certain areas. I'm not one of those people, I have to reduce the UT2 traffic levels pretty low in many places to achieve 25 FPS or more, so low in fact that it's hardly worth having any traffic on at all sometimes, that's why I've switched back to MyTrafficX 5.2a there is nothing that comes close to it performance wise, not even JF's Traffic X.

So some people have problems and some don't. Maybe there is some common thread between the systems that have pauses and ones that don't? I'm not talking about a frame rate hit due to ai - there is a very big difference between a frame rate hit and sudden pauses down to 1fps. As one of the people that has experienced pauses with Active Sky on a properly configured system, it can be frustrating trying to explain the situation. Reducing the ai% is not a cure if your system is powerful enough. In ASA, I can fly at 30fps in any cloud situation but when ASA loads weather, I get 1fps pauses. Sounds like a similar problem to me. Although I don't fly FSX, I did have the same issue with ASX - of course, the fps were much lower to begin with becuase of my old system. The reason that I point to ASA is it is the only program I have that is running in the background that periodically injects a large amount of information in to FS. Sure, other people have things running in the background but I can't think of anything that is more taxing than ai or weather.I don't know what the answer is or if there is an answer. It just seems like it may be worth looking in to. The point is, 1fps pauses and fps slowdowns may be two different animals.

I want some of what you're on. That is the most ridiculous thing I have ever read. No performance hit with 70% AI turned on compared to no traffic at all is what you're saying right? Even Aces themselves said the biggest hits to frame rate in FSX was from AI planes and ground vehicle traffic. I also have no clue how to mipmap planes that imo should have been already mipmapped by the developer. If it's so easy to do then why didn't the dev do it? Aerosoft's scenery also isn't mipmapped. About the only superb quality addon that I have purchased in the past few months, and believe me I have purchased a bunch of them, is Fly Tampa's Kai Tak. Superb in every way. All the other vendors could learn a thing or two from these guys. Those aerosoft addons were pitiful, cost me a small fortune, and their support was even worse. I am tired of being ripped off by low quality flight sim addons. It truly is no wonder people pirate this stuff so much. I wouldn't have bought half the addons I did in the past few months if there was a try before you buy. Some of them even got high marks in reviews from avsim which makes me doubt the objectivity of the reviewers in some instances.
