I got my PNY GF4 Ti 4600 about a month ago. When I played D3D games I noticed major texture blurs, tears, and sparkles. Text would smear, textures would be left unshaded, everything looked like a disco. In other words, D3D games are UNPLAYABLE. I found the quickfix solution to this shortly after. Simply pull out DX8.1 and put 8.0a back in, and all the problems go away. Of course, I can't play DX8.1 games now 
I mostly play OpenGL games anyway (quake 3 engine), but I had a couple friends over and we were wanting to play a few DX 8.1 games. Well, I was going to stay away from it, but I figured hell, nvidia probably has some updated drivers out that fix this problem. I install DX 8.1 and go get the newest nvidia refs, and I still have this problem.
Anyone else in the same boat? I've read about quite a few people having this problem on Dungeon Siege forums, but I have yet to see any bitching anywhere else.
