[Vista] Garbled graphics. HELP!

[Thaliur]

in which way are they garbled?
It could be a texture problem, shader issues, artifacts... almost anything ^^
A screenshot would help immensely.

Some general advice:
Try the newest official drivers
check the temperature
try other games with similar requirements
try switching off certain effects (AA, screen grain, bloom...)

Though these might not solve your problem, they might help tracking it down.
