Cryostasis on HD4870

[lukankata]

Hello, everyone!

I bought Cryostasis. But i have some problems with it.
I experience some weird graphical glitches. In the beginning i have those green artifacts on walls especially when my flashlight is switched on. And the light sources are not displayed properly. The light coming from them is like a black spot with gamma of different colors around it.
Using Catalyst 8.12 official + vista ultimate 64bit.
I have no problems with other games and have barely clocked my card.
Am i the only one ATI user having this issue at hand? I really hope it's a game's problem that needs some patching.
