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.

guzugi 03-30-2004 08:59 PM

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. :-/

sharpie 03-31-2004 06:45 PM

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?

guzugi 03-31-2004 09:07 PM

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.

gaborn415 04-16-2004 12:54 PM

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.

guzugi 04-16-2004 03:17 PM

Yuck! Lets hope that maybe ATI will come out with a new version. This is pretty bad :-/

sharpie 04-16-2004 05:05 PM

gaborn is UT2004 the only game that suffers that much of a performance hit, and have you tried any other games?

trey85stang 04-16-2004 06:56 PM

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:

RHLinuxGUY 04-16-2004 08:09 PM

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.

derfunkenstein 04-17-2004 11:06 PM

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...

gaborn415 04-18-2004 12:47 AM

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.

UnTamed 04-18-2004 06:30 AM

Your best option for UT2004 or any "UT2 engine" based game for that matter is version 3.2.8 .

...if they work for you.

derfunkenstein 04-18-2004 04:21 PM

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
