VESA better than FLGLX?!


Good day!

I have just "upgraded" to Fedora Core 6 (after a short break from linux) and is now sitting here tearing my hair out over fglrx...

When I was to install the driver(s) with ATI's "wonderful" program it told me I had an "unknown X server" (I have X.org sumt) which made rethink and download RPMs for fglrx (both x64 and 32 I followed a guide). After that I ran aticonfig and boom it seemd to work. However according to glxgears VESA gives me ~700 FPS (too high?) and fglrx give me ~650 (to low?)...

On my first Fedora boot (after install) I was greeted by an "OUT OR RANGE" error which made me config xorg.conf myself. Could this be the problem?

Perhaps someone with a Radeon X1600Pro (like me) or similar card could share their xorg.conf? Fedora's own xorg.conf-creator just throws me to "out of range" again...

Thanks!

When using fglrx drivers,
Code:
glxinfo
should say, among other things, that DRI (Direct Rendering Infrastructure) is enabled and the driver should not be Mesa but your ATI driver instead. This is when the driver is working all right, and you should get high fps. If the driver is Mesa or especially if DRI is disabled, you'll get low fps. VESA driver is a low-resolution low-performance driver, and if your fglrx gives same level fps than VESA driver, you have something wrong.
