I just tried Crysis Warhead DX10 on Windows 10 with the Framelimiter enabled and it is working without crashing using a R9 290X card. I do not have Windows 8.1 installed currently.
I tried again today in a later level, it still crashes. I will try the new drivers, maybe it can sort it out.
EDIT : Same with Catalyst 16.7.3.
It looks like I have a similar problem with Bad Company 2.
No problem with the FRTC disabled, I launched the game with it enabled, it started, but froze quickly. Now it freezes even before the intros. If I disable the FRTC, it launches and works.
I don't know which DirectX version the game is running with, but it's 10 or 11. I'm not sure the game properly uses DirectX11, couldn't this problem be related to DirectX10 ?
I tried the FRTC with R6 Siege, running in DX11, it works.
