I apologize in advance if this problem has already been addressed.
I've been having a strange occurrance happen during gameplay, where a section of a character stretches away from the model to a fixed point in the distance, like they're attached to some 3d rubber cord. It has happened in quite a few of my games, including Oblivion and Halo, and across several versions of the drivers.
My rig is as follows:
AMD Athlon 64 x2 4400+ (2.2 ghz)
ASUS A8N32 Deluxe SLi
e-VGA GeForce 7900 GT 256 meg
320 gig WD Hard Drive
