| |
Hi, I have a PPro 150->166 with bus speed 66MHz. I notice on loading proform.o (with kernel 2.1.82) that I get an improvement of 17.2->20.7 fps at 512x384 in q2test (Quake II Test). I guess thats a 20% increase but it doesn't seem THAT big...is that normal? High? Low? I'm also wondering if there are other regions besides the framebuffer than can/should be set to Write-Combining. I'm using XFree86 3.3.1 with a Matrox Mystique w/ 2Mb SGRAM. (Also, anyone think I could get an improvement by using the XSuse server?) I'm interested in this mainly as a benchmark...but perhaps my CPU isn't stressing the bus out cuz it isn't fast enough ;)
Thanks, -BenRI
