Sorry I am asking again but I didn't get answer.
This is my computer:
CPU- Intel core 2 quad QX9770
RAM- 2GB RAM
GPU- NVIDIA GTX470 1280MB
OS- windows 7 ultimate 64 bit

I installed 1.9 patch and DX11 and high res textures. I put ultra settings with DX11 and high res textures enabled and motion blur high. The game isn't working good. It sometims lag. I can't play it like I play it before the patch. Is my computer not good enough for Crysis 2? I know I have to add more RAM but will it do the game like before the patch? What I have to do?

Thanks.

Ur processer is little bit underpowerred. And you could use another 2 gb of ram

I get 25-35 fps on Ultra at 1080p and I have
i7 920
6gb ram
Gtx 570

So isn't it a problem in the patch? If you get 25-35 fps with your very good computer it's a problem in the game no?
