when playing the game, some textures are distorted, the crosshair is doubled side-by-side and explosions appear in obscure "colour blocks".

my system details:
- hercules kyro II 3d prophet 4500 64 MB tv out graphic card
-VIA chipset
-512 MB RAM
-the newest drivers are installed

neither the graphic card nor the chipset is mentionned at Yodas help desk, neither as supported nor as unsupported card and chipset.

can anybody help me?

thank you!
