Re: nvidia 256.52 xorg-server 1.9.0 performance regression
This problem seems to be card specific since I have a GeForce 9600 GT (G94) and it is fine on 1.9.0 with AA fonts but with my GeForce 9500 (G96) it runs like a slouth with AA fonts. The issue is not with composition since I've tested it just running xterm (with Xft support enabled) and metacity and turning off composition in metacity makes no noticable difference.
The G96 runs fine on 1.8.2 with AA fonts. Both systems are using identical binaries from source compilation. I've attached bug reports from each systems. I would blame my system as it has a lot of old versions on it but as other people have reported similar problems I'm fairly certain it is somewhere in the render acceleration paths.
