Playing TR now. I never updated my drivers still using 310.90.
Ive been reading that tesselation causes occasional crashes with a 600 series card for whatever reason. That and the exclusive FS option.
Maybe its actually driver related or driver/600 series combination thats the issue and not so much the 600 series card itself?
I havent had any issues myself and the game is stable and smooth but .. I have a 500 series and have Tess disabled & All else on Ultra and using normal hair.
TressFX looks good, but seems theres a lot of clipping at times. I found it annoying personally.
Plus it really kills framerates at least on my 570.
With all on Ultra and Normal hair, Tess Disabled the benchmark showed 57 lowest FPS and MAX 60FPS. (using Vsync tripple buffer)
All setting the same with FX Hair, it dropped to something like 34MIN 49 MAX.
At any count, Im only a couple hours into the game but so far so good. Its truly is a beautiful game visually.
