So, my hardware is this

intel i5 750 @3.8ghz
6gb ram ddr 3
nvidia gtx570 direct cu II


I put the righ res textures pack, and the dx11 patch, updatet do version 1.9

I start the game, plays a little, and then black screen, and the game freezes why ?

In other games like Witcher 2 all things is ok, no black screens, nothing.

Is anyone having this problem ?

Same problem here, but my game even starts... tryed it on game notebook and desktop pc

To much overclock GPU? For any reason GPU is not stable? Motion Blur manual deactivate in Autoexec, so i btw get Black Screen if i get wounded at last Patch.
Try different Driver and or if u not OC the GPU is not working correct perhaps (try to underclock Memory or Cores with Afterburner).

It can be so much.

Edit: Ahh forget overheating GPU, then probably Driver reset. If u got Black Screen wait few minutes cause reset Driver need some time. Also try run Taskmanager and then go back at Game.
