Hi anunaki, welcome to TSF
Please post your system specs and graphics card driver version number. (See
here for the specs we need)
Do any of the affected games have a config program that can be run before starting the game for settings graphics options?
Is this a new problem? Have you made any system changes recently?
Go to Start > Run > dxdiag > Display tab and run the DirectX tests. Any problems listed in the Notes box?
