    I've noticed that the framerate limiter in BeamNG kills performance. It makes everything a lot laggier vs using just vsync. Is this normal? In many games I've played its vsync killing performance more than the game's framerate limiter...

    Even if you use Afterburner's fps limiter, that increases CPU load a lot, decreasing performance. I wonder if FPS limiting in BeamNG limits just what is drawn to screen, not what is actually processed.

    Vsync seems to limit what is processed.

    Still it is bit odd how fps limiting creates such high cpu usage, I think it was mostly on one core, but can't remember now for certain.


    I guess something like this:
    If everything runs at 100fps on background and with limiter you are limited to 60 that is drawn to screen, CPU delay causes GPU to wait more and lag not being able to put 60fps on screen, which it can do just fine with vsync.

    However this does not necessary occur, I remember that when I did test, there were conditions that had to be met, but I have forgotten which they were as I did not pay much attention to issue.

    It tends to introduce some microstuttering.
    What I suggest is to set it 2-5FPS higher than your target.

    I've tried that. However, that does not eliminate the stuttering. I'll stick with vsync. I just wanted to know if this was a known issue or not. Also, does it affect some hardware more than others?
