I am having problems with the graphics of STALKER clear sky and STALKER shadow of chernobyll. The images and objects seem to drag along the screen when I move. The first time I played stalker clear sky after installing it, it worked OK but it was lagging, so I restarted the game and changed the settings. Then when I started to play the screen was like this: http://img217.imageshack.us/img217/1828/sseskil092808111232marssd3.jpg I have tried changing settings, reisntalling Nvidia drivers, resitalling directX, reinstalling the game etc.etc. but the same thing happens. Then I decided to isntall the previous game, Shadow of Chernobyll, and the same thing happened. These are my Specs: Intel Core 2 Duo T8300 2.3Ghz Nvidia GeForce 8600GT 3GB RAM OS Windows Vista 32bit. It is a Lenovo Laptop. Other games work correctly, such as MOH Airborne and Crysis. What can I do? Im getting real desperate, as I bought the game from Steam and cant play.
