Re: crappy performance with 100.xx.xx series.
I also notice a performance hit using the nvidia 100.xx.xx series drivers using my 8600 GTS. In warcraft i previously on my 7600 GT had 0 issues and the game ran smooth except in heavily populated areas but still fairly well. Now the game slows up randomly so that its just plain choppy and after a few seconds, its fine again. its very odd. i am using a stock ubuntu 7.04 install, i removed the driver packages and installed the 100.14.11 drivers as per the instructions in the sticky post.
edit: also in wine and cedega, running the game in d3d mode causes my mouse cursor to flicker, where before with the 9x.xx drivers it wouldnt.
