Hi thereI have been a longtime lurker around here. I have recently gotten back into Flight Sim after a long hiatus. I have been doing this a long time but I am just now getting back into it with a new system and a steep learning curve. Could really use some help right about now. I have exhausted all search functions on all forums that I can find and it is becoming a bit of a merry-go-round!! Too many contradictions and now I just feel like I am "going fishing with dynamite" as my original issue was not that big.My system - i7 [email protected], Z68x-UD3H-B3, MSI GTX560Ti Hawk OC@950mhz 1gb, G.Skill Sniper 2x4gb DDR3-1600, OCZ Vertex 2 60gb SSD, 2x1TB wdc Black, Antec Kuhler H20 920 Cooling, OCZ Memory Cooling, Cougar 700CMX 700w PS, Corsair 600T White CaseMy basics - FSX Gold sp2/accel (FSX on 1tb dedicated drive, win7 on ssd, 2nd drive storage) - REX, Orbx, Aerosoft, Iris, DBS w/f, etc,etc. - Setting mostly high to max - Resolution - 1920x1080 on a 24" Asus monitor - Tweeks - Well, there in lies the problems!!My problem - At first, none really, then I started to fiddle!! haha (basically Jerky AI planes in game and using fs recorder)My initial setting where pretty basic. A stock .cfg (with 2048 max texture for REX, etc. and thats about it) and using some of Nickn's advise but found my system worked best with unlimited frames (no nhancer/inspector) AA set in-game, ansitropic in-game and mostly "application controlled" settings in the nvidia control panel (NO v-sync). These setting provide 100+ frames and amazing smoothness. That is until I encountered some heavy REX clouds, then BOOM, it all went sideways. My gpu overheated and shut down with a black screen! After some research, I discovered that limiting the frame rates in-game to 60 solved this problem. It did create another problem though. Screen tearing. To solve this, I enabled (v-sync force on) in my nvidia control panel. Problem solved. Everthing was great for a bit. Smooth, no problems, etc.Then I encountered traffic. The "AI" did nothing to my framerates as my machine is a beast. The problem was that the "AI" looked like they where having an epileptic seizure. Forward and backward lunging and stuttering like crazy. I also installed FS recorder at about the same time I noticed this. Using that program and "record as traffic", the problem was even more pronounced. This made me crazy and I looked for a fix. The fix I found was that if my limited the FPS (in-game) to 30, problem solved. No more "seizure AI". New problem though!!! Now my terrain was stuttering!!! This is where I began to research BOJOTE and all of his fixes and tweaks. I decided that maybe I should use an external FPS limiter and run my .cfg through his nifty little website device. I proceeded to install Nvidia inspector and send my .cfg through the Bojote tune up shop. I also limited my FPS to 30 using the new nvidia inspector.Well that brings me to the present. After doing these last few tweeks, I fired up FSX and discovered that it was running like absolute CRAP!!! Barely able to make 25fps stable and jerking like 1920's black and white movie!!!!!!!!!All of this, just so I could make a little AI airplane stop jerking a little bit. I literally took a machine running FSX at over 100+ fps steady with sliders maxed and reduced it to a crying sad shell of it's former self.I believe there is a lot of value in the tweeks from people like Bojote and Nickn. The problem for me has been the contradictory info and opposing views but mostly my impatience for a fix for the AI problem. I am lost in the middle somewhere and only because I want to fix a VERY SMALL problem. Like I said at the beginning "Fishing with dynamite!".Sorry for the long read. If anyone has been patient enough to read all of this and could point me in the right direction, I would be eternally grateful. I am honestly lost. All I want to do is smooth out the "AI" visuals and maintain my 60fps limit with AA and v-sync enabled. Also be able to record some video with FS recorder and have smooth AI. I know my machine has the horsepower but I just think that there has to be a simpler way to get the AI to fly smooth without limiting the frames so much, or do all this tweaking OVERKILL!!Thank you so much for reading and any input is greatly appreciated.Eric

Life lesson #37430429: Do not tweak FSX via the CFG. :smile:Frank

Haha Thanks FrankI have already reverted back to stock .cfg and gone back to in-game 60fps limit, aa, ansitropic. It''s all good again, except for those pesky epileptic AI. There has to be a simple fix, I just know it!?!!....... Ideas anyone?

Everyones AI is crazy sometimes...Once I saw a A321 take off with the cargo doors left open!

Ya they are strange. Its just that I know the power is there, something is just not working right. For example if I am in slew mode the AI are perfect and smooth or is I lower my FPS limit to 59 instead of 60 they are much smoother. Not at 58 though then they jerk again!!? 56 is good but, 54 is better!! I mean it is just crazy, I can't understand how they work. I am about to purchase UT2 but I am holding off until I get this sorted. Also, I just love FS recorder and I can't seem to get the AI versions of my plane to not stutter. It doesn't seem like a lack of frame rates either. If anything, its the opposite. TOO MUCH POWER. Like fps spikes rather than delays. They want to surge forward. Now I understand that the more consistent the fps, the better, but it doesn't seem to follow what I am seeing on the screen as far as my fps counter. It is pegged solid at 60fps (maybe 60.2 here and there!) but the AI are doing there seizure thing anyway!?.....so weird. I guess I am just hoping that someone has an idea. Something simple....like "oh, just enable LOD clamp" and presto, its fixed. I guess I can dream, right!

Hmmmm... that's an interesting statement, Frank. :( Care to expand on that a bit?

Not having much else to do, I looked up your reference 37430429 suspecting some hidden Satanic link. :( However the most interesting thing I found was a site proposing "Lash Recovery Serum" http://www.shopmania.co.uk/women-cosmetics/p-lash-recovery-serum-4ml-priori-37430429Now I'm not too sure what this is for, but really hope you havn't been using too much of this stuff Frank......... :(

Maybe if you don't know what you're doing.

i was having problems getting my sim smooth until i ran across this website...http://fsxtimes.wordpress.com/ i dont know what happened but after bojote's tweak, i changed the RejectThreshold to the 512xxx my sim got sooo much better..im still not done the tweaking yet as i have to install active sky 2012 and globalX...currently running with nickn setup UTX and LevelD 763...good luck and i hope your sim gets better again with the crazy AI...Dont give up

Hi guysThanks for the replies. It appears Frank ruffled a few with the .cfg comment! haha! I have always tweeked my .cfg in the past with FS2004 and FS9 even with FSX on my last system a few years ago. The thing is, I tend to lean towards the sentiment that you can "buy smoothness but not tweek smoothness". That is why I got this machine and for the most part, I have been right, in my "much less than expert" technical opinion. Out of the box, it performs like nothing I have every seen. In my 15 years or so of doing this, I have never experienced performance like I have now. It's just the small things that are tricky and I think that maybe some (key word - some!) tweeking can help. The problem is my addictive personality and my desire for perfection (which I am certain many in our hobby possess!) I don't just stop at one tweek, I do everything, test, do more, test, and finally I realize I may have done too much!!!!! haha Long story short, after posting last night, I continued playing around and was able to fix my problem about 95%. I lowered my in-game AA to 50. It has maintained my terrain smoothness and overall fluidity and it has made the AI planes fly smoothly. (There was a lot of testing involved!!) As for FS Recorder, I changed the "recording interval" which I had set to the max of "1 frame" down to "1/8" and it made a complete difference. Smooth recorded "traffic". I also think the lower setting of 50fps in game helped that as well. Anyway, I think I am pretty satisfied at this point. Smooth AI and killer fps. For the record, the only tweek in my .cfg is the "AI sound improvement" by Bojote. Sound lod=1. Also the texture max load= 2048. That's it. I am throwing away the key and never opening that .cfg door again. Well....... that is until I install UT2!! hahaEric

Excellent, Eric!It's also not so much as 'not tweaking the cfg', as putting into it what the ACES team didn't get chance to put in: Frank appears not to realize an awful lot of the hardware has changed since the original FSX was introduced - as has been the case with the operating system. There wasn't much point in adding "BufferPools=0" when the video card was an Nvidea GeForce 3 Ti-200 AGP - or even the revered 8800, and you were barely able to run FSX water at High 2.x with a C2D e6600 at 3 gig without sacrificing performance elsewhere. How about HIGHMEMFIX=1? That's a piecet of FSX which was "forgotten", but is an essential component in the prevention of cloud 'flashing'. AffinityMask? - didn't have (generally) quad-core procs 6 years ago. "WideViewAspect=True" - I know a number of 'simmers' that now have 3 x 47" monitors on their basement walls...Frank is being self-righteously naive in his comment, that's all.

Sorry if I puzzled anyone...I meant It as a joke but It is still true in many ways.Frank(I don't tweak FSX using the CFG)

Well I'm glad to hear that Frank!! I reckon you must have a keen sense of humour, and I.... am somewhat obtuse, I'm afraid... :(

LOL Frank! I have the US Cities Chicago installed and my AI Jets were on the ground, using the highway/freeway from the city to KORD!!! I don't know what that is about! Maybe Chicago people have a high speed transit to the airport???And I saw at least two doing this with the other only a few hundred feet behind the other!Daniel

Hi DanielThat is funny! Many years ago, I was using the original Ultimate Traffic and I was standing outside on a carrier deck (original moving carriers program of some sort) As I stood there admiring one of Dino's F14s or something, a British Airways 747 slowly passed by me about 200 feet away on the surface of the ocean at exactly the right height of a boat (even creating a wake!!) It was the strangest thing and had me thinking I had just been doing a little too much flight simming! lolEric
