Artefacts and Graphic bugs, unplayable

[Bushlurker]

I have this exact same issue too... both with the last beta and the new 1.04 patch...
Card is an Nvidia 8800GTS - latest drivers - win 7 RC 64bit & 4GB ram - maxmem set to 2047... Temps are fine - card is never higher than about 68 degrees...
It happens randomly from about 5 minutes up to about an hour or more after starting play... Occasionally it comes and goes, but eventually always gets worse until eventually the game crashes...
No idea whats causing it... it's certainly not temperature and I see from this thread the same problem reported by ATI and Nvidia owners... that makes it unlikely to be driver related... I've only 4GB of ram so that makes it unlikely to be purely 8GB ram-related.....

Anybody got any other ideas???
