The performance issues - even more complicated

[TheRat]

So as reported I share the same issue with DCSWorld 50% framerate compared to DCSA10 -but here comes a new effect (unknown to me):

 

I was fiddling with a bunch of different setups and checking the performance - with each time only playing for a few minutes. The next try I was circling on a constant altitude with FPS around 27 (GPUs @60%) when the framerate jumped suddenly to 90 FPS (GPUs>90%)! I kept circling and after a few minutes (a few cycles - so it had nothing to do with the terrain) it jumped back to below 30 FPS. This pattern is alternating jumping eventually back and forth (1 to 5 minutes). I could not find anything corresponding to that effect. With vsync this effect is of course clipped at 60 FPS.

 

In DCS A10 I get constant framerates @60 (VSync). So - explain that...

 

EDIT: maybe related to that bug http://forum.lockon.ru/showthread.php?t=89061

Interesting, I will have to check what driver version I am on, I been working on a tank mission and the frames have been about 40-60 when I jump in to look at the mission but out of the blue last night my frames were 80-100 lol... dunno :)

Now tried different drivers versions including beta - no luck. The strange thing is the framerate jumps instantly from e.g. 30 to 60 frames and eventually back. Tried w/ oder w/o vsync. No luck. This is a bug - an annoying one.
