ATI fglrx performance is crappy!
I finally got the fglrx drivers working from ATI on my Fedora Core 1 system for my new Radeon 9600 Pro and i'm not too impressed while playing UT2004. I think there might be a problem in the way in which either the driver is configured or with the driver itself. The output of fglrxinfo is:
[eric@gecko eric]$ fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: RADEON 9600 Generic OpenGL version string: 1.3 (X4.3.0-3.7.6) I see that other people get more specific info for the "render string" portion other than "generic". Is this possibly a driver problem? I see people saying not to use the latest drivers for Fedora. Or might it just be my configuration? Any thoughts? |
I'm also gettting crappy performance, less than 20FPS, and under Windows I get over 60FPS. I also have a 9600 Pro, albeit a mobility version. I'm using the 3.7.0 under Slacwkare 9.1, I'm gonna try installing the 3.7.6 later tonight, although I've heard other people, including yourself saying they still get crappy performance. Here's my fgrlxinfo output:
display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: MOBILITY RADEON 9600 x86/SSE2 OpenGL version string: 1.3 (X4.3.0-3.7.0) Mine doesn't say generic, but something's still wrong. Could you try typing in glxgears, or fgl_glxgears and tell me what FPS you get. I get around 60 in each, but I think the reason for being so low is because when I setup fglrxconfig I told it to VSYNC. |
for glxgears i get about 2400 fps and for fgl_gears i get 300-400 fps.
How fast is your processor? I am already using version 3.7.6 of fglrx. :-/ |
I turned off VSYNC and I'm getting around the same score as you in glxgears and fgl_glxgears...
My processor is a Pentium M 1.5GHZ, the speed is roughly equivilant to a Pentium 4 2.4GHZ. From what I've seen our speeds in glxgears and fgl_glxgears is pretty good, which leads me to wonder if the problem is with UT2004. I don't have any other games installed to test, but I'll test one soon. Do you have any other games you can try? |
Well, looking back on some tests with different maps in unreal, it does seem to depend on the map. The small indoor ones perform quite well, while the large outdoor ones ones run quite sluggishly. I thought it just might be a loss as compared to windows where in windows it is using DX9 and linux is stuck to OpenGL. I guess it would be the game, but i expected to get quite good performance :-/ It's still better than my GeForce 2.

Talk about crap performance, I'm on a P4 2.8 with HT enabled running a 9800Pro and I'm pushing 20 FPS in UT2004. Is there some way to optimize my performance? I usually get around 50-60 in Winblows on the same settings.

glxgears gives me -
18352 frames in 5.0 seconds = 3670.400 FPS 21139 frames in 5.0 seconds = 4227.800 FPS 21119 frames in 5.0 seconds = 4223.800 FPS 20972 frames in 5.0 seconds = 4194.400 FPS 20405 frames in 5.0 seconds = 4081.000 FPS 21180 frames in 5.0 seconds = 4236.000 FPS 21095 frames in 5.0 seconds = 4219.000 FPS 21225 frames in 5.0 seconds = 4245.000 FPS and fgl_glxgears gives me this 3459 frames in 5.0 seconds = 691.800 FPS 4334 frames in 5.0 seconds = 866.800 FPS 4507 frames in 5.0 seconds = 901.400 FPS 4490 frames in 5.0 seconds = 898.000 FPS 4474 frames in 5.0 seconds = 894.800 FPS 4489 frames in 5.0 seconds = 897.800 FPS 4350 frames in 5.0 seconds = 870.000 FPS So I dunno if it's my drivers or what as I have no frame of reference for these benches. All I know is I'm regularly dropping below 20 fps in UT2004 and that never happens in windows, I can crank AA to 6x and Aniso to 16 and it can get down to thirties but I never see 20's or worse like I do in Linux. |
Yuck! Lets hope that maybe ATI will come out with a new version. This is pretty bad :-/
|
gaborn is UT2004 the only game that suffers that much of a performance hit, and have you tried any other games?
|
i know this wont help you... but i strongly advise against using ATI cards in linux if you are a gamer. Nvidia cards all the way here... btw i get about 25-30 fps with a geforce2 mx200 w/ 32mb of ram in UT2004 :cool:
|
I get 2216 in glxgears, and in fgl_glxgears i get 307-356. I have the newest ATI drivers 3.7.6, this is the first time i ever installed the ATI drivers out of the box, downloaded and installed it in RedHat linux 9, with the stock kernel it came with! Games emulated work (supposedly the old ones couldn't play emulated games for some reason) like Warcraft 3 and Steam works fine just a little sluggish here and ther, Enemy Terretory works fine, and I tried the UT2004 demo and I turned most of the features off and its not sluggish at all in big open areas.

I've got the same problems with 3.7.6 as you guys do. Here's what I'm running:
Athlon XP 2700+ MSI KT6V KT600 board 512 MB PC3200 Radeon 9800 Pro Slackware 9.1 in fgl_glxgears I'm getting 737.800 and in glxgears I get 4673 (both of these in a window) and in UT2k4, I drop down into the 20fps range. It's retardulous! At least it doesn't crash anymore... |
well since I con't go buying a 6800 Ultra right now I'm kinda stuck with my 9800 Pro ;). I don't have any other games for Linux actually just switched over to using Linux what would you suggest to check out? Also is there anything like in the driver or perhaps in fglrxgonfig that I should set? Like the advanced options should those be on or off? Uggh the performance really is just craptacular.
|
Your best option for UT2004 or any "UT2 engine" based game for that matter is version 3.2.8 .
...if they work for you. |
Well I downloaded 3.2.8 and actually it isn't too bad. On my system, I'm getting 45-80 outdoors and 60-150 (fluctuating heavily) indoors. Beats the crap out of the 19 I bottomed out at with 3.7.6
