Recently downloaded the demo to see if it would run, but it does not run correctly.
The screen flickers (on the right hand side, it flickers between the background and a standard window). The mouse does not move smoothly but studders slowly to the point where the game is unplayable.
It runs fine on another PC with less memory and inferior specs.
Running on a GeForce FX 5600 with fully updated drivers. Using Vista but it will not run in compatability mode either.
