Question Poor ATI Performance

Hi Guys

No matter how hard I google I cant find a remedy and its driving me crazy. I have a 9800XT but it doesn't seem to be working properly. I can only go as high as 1024x768 in games and the glxgears and fgl_glxgears benchmarks show that it looks like the CPU is doing all the processing rather than the GPU. I have the latest kernel (2.6.17-1.2157) and drivers (fglrx-kmod-8.26.18-1.2.6.17_1.2157) and a trusty nForce2 based motherboard.

$ glxinfo | grep direct
direct rendering: Yes

$ fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9800 XT Generic
OpenGL version string: 2.0.5879 (8.26.18)

$ glxgears
7990 frames in 5.0 seconds = 1597.996 FPS
7938 frames in 5.0 seconds = 1587.448 FPS
7947 frames in 5.0 seconds = 1589.312 FPS

$ fgl_glxgears
Using GLX_SGIX_pbuffer
1557 frames in 5.0 seconds = 311.400 FPS
1800 frames in 5.0 seconds = 360.000 FPS
1795 frames in 5.0 seconds = 359.000 FPS

EndSubSection

I've also attached my xorg.0.log

Any help at all would be appreciated as I'm considering giving up soon....I dont wanna to go back to Window$

glxgears is no benchmark and this numbers are faster than pure sw rendering.
in your log I can fine any errors too can you provide some real benchmarks and the output of dmesg?

Hi
I know glxgears is a bad benchmark but I dont know how to run any others. I've heard of the Enemy Territory Benchmark but I can't get it working.

$ /bin/dmesg | grep agp
Linux agpgart interface v0.101 (c) Dave Jones
agpgart: Detected NVIDIA nForce2 chipset
agpgart: AGP aperture is 256M @ 0xc0000000
agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0.
agpgart: Putting AGP V3 device at 0000:00:00.0 into 8x mode
agpgart: Putting AGP V3 device at 0000:02:00.0 into 8x mode

]$ /bin/dmesg | grep fglrx
fglrx: module license 'Proprietary. (C) 2002 - ATI Technologies, Starnberg, GERMANY' taints kernel.
[fglrx] Maximum main memory to use for locked dma buffers: 929 MBytes.
[fglrx] module loaded - fglrx 8.26.18 [Jun 22 2006] on minor 0
[fglrx] AGP detected, AgpState = 0x1f00421b (hardware caps of chipset)
[fglrx] AGP enabled, AgpCommand = 0x1f004312 (selected caps)
[fglrx] total GART = 268435456
[fglrx] free GART = 252440576
[fglrx] max single GART = 252440576
[fglrx] total LFB = 121630720
[fglrx] free LFB = 100659200
[fglrx] max single LFB = 100659200
[fglrx] total Inv = 134217728
[fglrx] free Inv = 134217728
[fglrx] max single Inv = 134217728
[fglrx] total TIM = 0

The thing that bugs me is that everything looks fine!

EDIT: I just ran an ET Demo (http://www.3dcenter.de/downloads/ene...tory-radar.php) and got 2896 frames, 77.2 seconds, 37.5fps @ 1280x1024 with low detail settings. This should max out at my MaxFPS setting of 76, the 9800XT should be able to handle it! BTW...If anyone has trouble with a slow mouse in games, like it needs to 'catch up' to where your pointing, set 'seta r_finish "1"' in your config. This worked for my ET!

I wonder if I've inadvertantly got Antialiasing or anisotrophic (is that how you spell it?) filtering going?

Heres a GPU roundup from a few years ago that shows a little of how it should perform. My guess is these tests are dont with full detail rather than mine which I did at minimal...
