Could there be a reason my OpenGL is working so badly?


I just installed my video card drivers for my ATI 9550 on SuSE 10. The OpenGL works, just terribly. I get around 1100 fps with glxgears, and everything from the Doom3 demo to Stepmania to Starcraft in WINE and Cedega run just terribly. Is there a reason for this? Or is the reason just because it's a terrible card that's not supported very well for Linux?

The drivers do not work well in Linux. Are you running "Linux" drivers or emulateing using the Windoze ones?

I'm using the Linux drivers that ATI releases.

I have noticed that many linux users seem to prefer nvidia cards (and I'm very happy with mine). This might be why.

ATI card in Fedora 4

I'm having a similar problem too. I have a genuine ATI Radeon 9600 xt. Fedora 4 detects it and installs it as a Radeon 9600, but anything I run, there seems to be no hardware support. Anything from games to screensaves are jerky and look terrible. What can I do to unleash the full potential of this card in Linux?

Guess maybe my next card will be an Nvidia.

Yes...Ati support is extremely sub-par on linux. But your fps on glxgears still seems low, I have a laptop with a
ATI Mobility Radeon 9000 AGP 4X and I get about 1300fps with Suse 10.0 and Ati's Drivers. (vs. 13,000+ with my nVidia 6800GT on my desktop ).

Make sure glxinfo reads "direct rendering: Yes" also did you follow the Suse instructions on installing it?

I used the directions from susewiki.org. They seemed to be working great until I tried to run really graphically taxing applications (Quake 4, Doom 3, and anything in Cedega). I think I'll be purchasing a 6600 gt sometime soon

Everything you mentioned (Q4, D3....ect.), they are all extremely taxing on a video card. Your Ati coupled with their drivers that are not up to snuff, may not be up to task. On windows they probably would run. I highly recommend nVidia for such games on linux. Keep in mind at 1280x1024 with high settings, Quake 4 slows me down in spots to 35-38 fps. And my home box is no slouch (AMD 3500+, 2gb ram, 6800gt pci-express).

I guess I just expected the Linux native games to run better than they do on Windows, since the operating system doesn't take up as much system resources as Windows does. I never thought that a video card could work worse or better under different operating systems

Actually with an nvidia card that is true, at least in my experience with Quake 4. It definitely runs better on Linux vs. Windows. I had it initially installed on Win (preordered the game) with some very strange artifacts and visual issues (ended up installing beta video drivers, help a little) but with Id releasing the linux client two days latter, I quickly transferred the install to Linux. And it runs like a dream (with enough hardware under the hood ) on my Slackware box.
