I must share this experience with forum!
Today my son, who's M$ user for the first time asked me to help him with Slackware installation. I also noticed that he already had SuSE 9.1 installed and he didn't mind it to be removed. I don't know what struck me but I backed up XF86Config from SuSE on diskette. After installing Slackware 10 I tested that everything worked an suddenly I saw the displeased face of kiddo because of 3D rendering.
Everybody, who has ATI, knows that it works miracles under Windoze, but on Slack this issue is really pain in the a##!
I definitely didn't want to look idiotic before my son, so I told him to go for a walk and come back in half an hour. (He knows I've been using *nix systems for 4 years now.)
THE SOLUTION PRESENTED ITSELF!!!
1. I removed xorg.conf from /etc/X11 and replaced it with XF86Config from SuSE 9.1
2. Renamed XF86Config to xorg.conf
3. Edited newly "created" xorg.conf for the mouse settings, changing Option "explorerps/2" to "IMPS/2" and editing "Device" "/dev/input/mice" to "/dev/mouse"
I saved my handywork and Miracle!; it loaded up after reboot WITH ATI 3D acceleration enabled!!!
I checked glxinfo and saw that direct renderind is enabled.
I simply could not believe my eyes. Test on small window gives
66348 frames in 5.0 seconds = 13269.600 FPS
65022 frames in 5.0 seconds = 13004.400 FPS
Test on fullscreen gives
2449 frames in 5.0 seconds = 889.800 FPS
Here is the shot as proof because I had some people making comments about the credibility of this post: http://eo.yifan.net/users/t/wdesborough/Screenshot.png
Test on Tuxracer gives roughly 1000 FPS http://eo.yifan.net/users/t/wdesborough/tuxshot.ppm
I felt like jackass
This means that all these years I simply didn't know how to properly edit X server. It appears that Slack comes with already installed excellent ATI drivers with 3D support. And there is only matter of proper editing and the ant in screensaver "Antspotlight" doesn't crawl, it runs like crazy
Here is the lesson for the master. Solution sometimes can be really simple and taken from history books. You CAN "Cut the Gordian Knot" as did once Alexander The Great!!!
P.S. And again I must emphasize my point here. I posted that report of mine not to be judged for credibility but to share my experience.
So you're using DRI. I must say those framerates seem unreal. Did you run QuakeIII, how many FPS on 1024x768 (full detail and quality options)??? What HW configuration do you have?? I'm using R9700Pro on 2.6.9 kernel with fglrx 3.14.6 and I'm very satisfied with performance but it is not close to what you have.
Use Qake3. You need Windows Quake III installation disc, and downlod linux binaries from id ftp (1.32b version). Start script and after it is done copy required files from disc. Run it in console as "quake3". You can set it up in "System" and "Game options" menues. Use 1024x768 and maximum quality options (you'll figure it out). Run console (QuakeIII console) by AltGR+ 1 (on alphanumeric part of the keyboard). Put in these lines:
\com_hunkMegs 256 (half of the ram usually)
\cg_fov 118 (this is an example and is not required if you're not used to fov)
Restart game and run few maps. Pay attention to the average FPS in upper right corner of the screen.
Run the timedemo:
After it is done run the console and read the average FPS in the last row of the output.
The section of your xorg.conf file you posted says your using a radeon 9000 (that's the BoardName "RV250 If" in the Section "DEVICE") which can make use of the FOSS radeon driver that's included in XORG/XFREE. Anything better than a Radeon 9200 (The Rv300, R300 or better) *may* work with the FOSS driver, but acceleration won't.
I find 13,000 fps to be fantastic. If you're getting that kind of framerate out of a Radeon 9000, I want to see what my 9600XT will do.... I currently get (what I thought was) a respectable 1924FPS using ATI's driver w/int agpgart, 1280x1024x24 resolution, 2.8HT Pentium, 1GBDDR400.
3D rendering can be affected by *ALOT* of factors, some of which are screen size, colour depth, processor speed, memory, agpgart used on MB or video card?
So, question time:
1. What are your system specs? (nothing in-depth, processor & memory?)
2. Screen resolution & colour depth at the time of your test
3. Which Radeon are you running?
4. How stable is your system?
anything else you can think of?
I have to take this with a grain of salt untill it can be independantly verified....
