DarkFoss Posted September 25, 2006 Report Share Posted September 25, 2006 I've been mucking around all weekend trying to find a way to tweak the xorg.conf file to improve my cards dismal performance. A fortunate round of Googling led me to a couple new sites. 1 in particular really turned things around for me. http://www.phoronix.net/forums/showthread.php?t=151 The above forum has a guy that goes by dgvirtual made a script thats a gui front end for aticonfig . It's really an awesome bit of scripting it can be found here : http://www.kde-apps.org/content/show.php?content=43612 You'll need to install kommander if you don't have it already. It's a kde app and it's in the main repository under Graphical desktop/KDE . It's pretty easy to use.. it has to be for me to be able to use it :P I used it to save the original file with working AIGLX then went ahead and installed the plf drivers and used it to create a new working xorg.conf after backing that new one up you can litterally reinstall either back-up to toggle back and forth between AIGLX and XGL . I still have some minor tweaks left to do but it's worked out great. I went from a glxgear score of an average of 250 to : [larry@localhost ~]$ glxgears 42287 frames in 5.0 seconds = 8457.336 FPS 40190 frames in 5.0 seconds = 8037.881 FPS 40573 frames in 5.0 seconds = 8114.524 FPS 40574 frames in 5.0 seconds = 8114.646 FPS 40577 frames in 5.0 seconds = 8115.233 FPS 40561 frames in 5.0 seconds = 8112.111 FPS [larry@localhost ~]$ fgl_glxgears Using GLX_SGIX_pbuffer 5128 frames in 5.0 seconds = 1025.600 FPS 5615 frames in 5.0 seconds = 1123.000 FPS 5820 frames in 5.0 seconds = 1164.000 FPS 5814 frames in 5.0 seconds = 1162.800 FPS 5805 frames in 5.0 seconds = 1161.000 FPS 5811 frames in 5.0 seconds = 1162.200 FPS A nice improvement concidering I'm running my desktop at 1280x1024 FSAA enabled set at 2 and using the XV video overylay extention. ppracer averages about 110 fps with FSAA set at 2 as well chromium is a rock solid 50 fps. Too bad from what I've read the author is going to abandon this script since he has bought a laptop with intel graphics. I wish I knew anything about scripting, I'll really miss this when it's no longer able to function. It works well with the plf 8.28.8 drivers.It's also been ported to a few other distros but the generic script I downloaded works fine. I can't really write a how to yet since I'm still exploring the settings. The only negative so far is a bit of spotting at the edges of the OGL screensavers and at the configuration screen for ppracer nt during the game. Not sure if it's a settingsuch as "UseFastTLS" "on" or due to my monitor being Generically configured for now. I've rambled on enough for now hehe enjoy ! ps. Sorry if I've posted in the wrong place I seem to have a knack for it.. but even though I'm running rc2 this should help all ati users no matter what they are running.. I also posted this at Mandriva Quote Link to comment Share on other sites More sharing options...
DarkFoss Posted September 26, 2006 Author Report Share Posted September 26, 2006 I've posted more info at the Mandriva forum since someone asked a few questions rather than repost it all here's the link. http://forum.mandrivaclub.com/viewtopic.php?p=252243#252243 Also in that thread is my current working xorg.conf file and an explaination about a few things I changed after running the script.
