With OA this seems to be back with a vengeance. Even on my own in the editor I experience it on Takistan. 60 fps but I get this input/view port stutter when panning around, more so when I move to areas of more buildings or dense foliage, BUT still my FPS is well above 50fps in these areas. So why the jitter...stutter etc?
Mouse smoothing appears to me to be a BandAid trying to fix a much deeper problem. On my own in the editor if I turn mouse smoothing all the way down I get bad input/screen jittering. Turning it up helps the problem a lot, almost makes it unnoticeable. BUT, the more activity that is on the screen; walking around a town or playing a mission, the effect of mouse smoothing becomes less and game feels choppy/jittery etc even though my FPS are never dropping lower than 30fps. Why can the game not have smooth input without the need for mouse smoothing? And if we do need mouse smoothing why does it loose all effectiveness when the scene become more complicated or a lot of cpu calculations are occurring(eg AI)? Remember- FPS are still high.
I know people will suggest to adjust this, but I have played with various values and it makes no difference, so I leave it at default.
I know people will also say this is to blame. But I can tell you there is a clear difference between the two. For example; running around on your own in the editor at 60+ fps is not affected at all by streaming (maybe if it was on
Us users are constantly wanting more performance increases and optimizations. But I believe it is things like this stutter at high FPS that is causing a lot of the problems and complaints that BIS cant fix. What is the point in optimizing the game and getting better FPS if playing at 60 fps feels like 17 every few seconds? The problem is that the game does run at acceptable FPS, it just FEELS much lower most of the time which I believe generates a lot of these performance issues and complaints.
What made me post this was an interesting review of the Nvidia 460 in which they used Arma2 OA as a benchmark. They clearly sum up what has been bothering me about Arma2 since it was released, but I could never quite explain. The question is, what can BIS do about it?
During our testing, we found that optimizing performance in Operation Arrowhead was less about improving framerates, and more about improving the responsiveness of controls. With high settings, we sometimes observed relatively high framerates even when there was so much input lag and choppiness that the game was simply not playable.Framerates were admirable with both GTX 460s, but again, the raw framerate is not the most important performance characteristic for ARMA II: Operation Arrowhead. Control responsiveness can suffer when the system is overloaded, even if the reported framerates are high. This indicates that Operation Arrowhead is not particularly GPU-bound, though it is certainly demanding.
Please give you thoughts on the issue, thanks.
