I've got strange video artifacts in the game (Heroes 3). Horizontal lines of garbage that appear in the game and title menu when moving the mouse. Also some videos (fullscreen ones) are totally garbled.

All other games (I have like 150 installed) work fine. The only game with similar problems is C&C Tiberian Sun (free download from EA site). Why?

Computer: Intel Core 2 Duo @2.66 GHz, GeForce GTX 470 1280Mb, 4 Gb Ram, Windows 7 Home Premium 64-bit. Video Driver version: 258.96

Screenshot of glitches attached.

Have you tried the basic compatibility settings?

If you right click the game shortcut and go to properties, then the compatibility tab. Then try setting it to run under XP SP3, disable visual themes and desktop composition.
