That is very diaappointing. I have the 990X with a 590 card and get >100 fps in the 2D and 50 + in the 3D. Hitting a FlyTampa airport like Tampa, I dip a bit below 50 fsp but never < 35 fps.

Well, history is just repeating itself just like with every version of flight simulator. I remember when FS9 first came out, we all had fs98 computers (cause nobody ever used FS2000 or 2002). FS9 was very hard on our computers. Then, by the time FSX came out, computers had gotten better, and all of us were on fs9 with 100% payware environments and complex airplanes at 100+fps on multimonitor. Today I just flew the NGX KSFO-KLAX at a decent 40fps (been tweaking my config a little), and thought "well, looks like FSX is finally setteling down on current computers. By the time Microsoft Flight comes out, we'll all be running FSX so confortably that, trust me, migration will be tough. At least they say that, finally, Microsoft Flight will a complete new software made from scratch.... I doubt it. I reckon FSX still has some code left from FS98, and the same thing will happen with the coming versions.

FSX is the game playing which i'm demanding the less FPS.Lower than 35 in counter strike, i just shut off my computer.Higher than 15 is just fine in FSX.

Okay, I can no longer follow this thread without putting in my two cents. I have been tweaking pc's as well as Flight Simulator (from FS9 on) for many years. It is correct that Flight Simulator performs completely different than any other program, and therefore requires a different way of tweaking/fine tuning. There has only been one person here making the correct statement,; It is ALL about SMOOTHNESS, not fps. A system running fsx at a steady 18 fps will, in all circumstances, produce a much smoother, and therefore more enjoyable flight simming experience.A system running 60-100 fps can show frequent stutters, and therefore a less enjoyable flight simming experience. The trick is to come to a situation where the simulator is running smooth, disregarding the fps. Take the test and change settings within fsx WITHOUT showing the fps. When you get to a state where you experience a smooth running simulator, you can check the fps, and I will guarantee you that you will be surprised. For the remark posted that the difference between 25 and 30 fps is noticed, I have to say that I am about 99,99999 % certain that the poster ismis-interpreting his experience.He is not actually seeing 30 fps over 25 fps, but what he is possibly experiencing is that the sim is running smoother. As stated by others, the human eye will see any framerate for 24+ as continuos motion. At that level, the human eye does no longer SEE individual frames, Now that is a fact. Coming back to the smoothness: That is different for every hardware configuration and addon in use. On some pc's 18fps can produce a smooth simulator, and on other pc's it can be for instance at 30. What you want to achieve is a state where the fps is not jumping up and down between a very high and low fps. Is your fps jumping up and down between 25-50fps, you will most certainly experience stutters.It is inevitable to have lower framerates in more demanding sceneries with the same aicraft. But as long as the sim is running smooth, who care's. Again, it comes back to having a smooth running fs at whatever fps that might be. I don't have a high end pc. My specs are: CPU: Q6600 @ 3.4 GHzRam: 4 GB, 800MHzGraphics: EVGA 8800 GT, 512 MbActive Sky X.MyTraffic X With the recommended tweaks in place I achieve a smooth running sim at 18-25 fps at a busy airport, and 25-40 fps in the air. Still running smooth. That's my two (and a half) cents. Manfred Luederitz

I generally agree with Manfred's post above.How many fps is enough ?Depending what you are watching - staring at a still photo then even 1 fps is enough.Watching an old western movie and observing stagecoach wheels moving in reverse direction - even 24 fps is not enough to replicate proper wheel rotation.The problem with fps you get from FSX is that these numbers are averaged over a second or so. FSX delivers frames asynchronously, so even though the an average number may look good the individuals frames may have longer gaps between them which is perceived as stutter or not enough smoothness. If frames in FSX could be delivered synchronously then even 24 fps would be plenty enough specially that in a cockpit things are far from fast paced action.

If you have an Xperia X10 (which I doubt anybody has) like me, you would really know the difference between the FPS capped 30FPS the screen goes at and the 60FPS uncapped FPS that you can hack in. Same with shooting games. HUGE difference between 30FPS and 60FPS. For me, the sweet spot for performance vs quality is 30-35FPS. Anything under 22FPS is too poor.

Well i see a big diference between 20 and 40. I need at least 26 fps to be happy.

I don't know about you guys but 25 fps with Track IR absolutely sucks. With the mouse cursor hidden, the NGX has me in the low to mid 30's, so it is "acceptable". Ideally I'd want between 40 and 60 but my Q9550, DDR2 ram, and GTX280 just can't pull that off anymore these days.

What is your opinion on the method of limiting those frames. Externally, with FSX to unlimited? Or internally, just using FSX?

Question ! last week i read an article about framerate in PMDG NGX, can't remember where. it stated if i recall it well, that framerate in FSX has to be set at maximum and an external program ( for games) would initialze the best possible framrate in FSX or other games.Somebody know this external program ? there was a direct link in the article i read.

this is the one i use. http://www.kegetys.n..._antilag101.zip Edit: Best for use in windowed mode.

Thanks yes this was the program, what is your experience with it sofar ?

Some might disagree, but i find this one much smoother than the FPS Limiter 2.0 and it seems to control the fluctuations closer to your limit setting. Also it does not involve the need for Java to create a .bat file which is needed in Limiter 2.0 to run it in FSX. With Antilag you just drop a .cfg file and another file into your FSX root folder and go fly. You set your fps and render ahead by editing two numbers to your requirements and you're done.

what settings do you use ?

I'm at 30FPS and Render Ahead at '0'
