Hi: Previously, I had RH 9, nvidia 1.0-4496 drivers, and kernel 2.4.22 (compiled by myself) and everything worked great (nice, stable, no problems). Now I am using Fedora Core 1, and I am experiencing an extreme 2d performance loss. I am aware of the CC_COMPILER_MISMATCH and Xfree86-Mesa-libGL issues, and these are resolved. FC 1 comes with the same kernel ... 2.4.22 ... and just for the heck of it, I even compiled my own to see if it would rectify the problem. To get some kind of quantitative comparison, I created a 6 meg plain text file (called "foo") Then I did this : 1) Install "nv" driver 2) start X 3) open an xterm and maximize it 4) type "time cat foo" 5) Install the "nvidia" driver repeat 2-4 Here are the results of dumping that 6 meg text file using "cat" the "nv" driver 1 min and 2.5 seconds the "nvidia" driver : 2 min and 47 sec. I can't imagine the XFree86 "nv" driver being so much faster than NVidia's own! Here are some more specifics about my system: Chipset: VIA 686B / VT82C693A/694x [Apollo PRO133x] Card : GeForce4 MX-440 OS : Fedora Core 1 Drivers : 1.0-4496 Kernel 2.4.22 (of course) Also : (1) I am sure that the nvidia drivers are using AGP (according to lspci -vv, the "nv" driver doesn't even enable AGP!) (2) I am sure that I edited the XF86Config file correctly. (3) I am aware of (and solved) the strange compiler mismatch and library conflicts with XFree86-Mesa-libGL (4) XFree86.0.log reports nothing unusual (no missing DRI symbols) Thank you very much for any ideas -Alex
