I take it back!
I had texture corruption in Silent Hill 3 and Doom 3 with the newest beta (!) drivers.
I almost had a heart attack because of that, if you don't know why, check my tread:
Did I damaged my card with overclocking?I had the same artifacts in the games with my bad videocard!
I thought that I messed up my new card too, and that I need to buy a new one again!
The DNA drivers are much more reliable. Believe me.
