Note, theres virtually no difference between the drivers used for AGP (The difference you see fall down as statistical noise) and this would be the problem as I can tell it.

Bios is set as force 4x AGP mode (Linux has no agp8x support in 2.4 series)


So really, should there be no change between drivers, or is something quite messy here?
what desktop resolution you're running? it seems much too slow for GF4 mx

Also, the tip about disabling acpi did not work, neither did it help to install 2.5.72 kernel (with the fixes for the nvidia driver to make it run)

compare previous results with a athlon 1GHz, GeForce2 MX 400 card on a via kt-133 chipset :
1024x768, 24/32 bpp
glxgears:
4557 frames in 5.0 seconds = 911.400 FPS

This is a real dead end.
the software we got doesn't help. The problem is we can not find the cause of the problem otherwise it would have been fixed.
so is there anyone know of any opengl diagnostic software or could write one?

I have the same basic problem...dual boot win2k and Redhat 9.

In windows quake3, i get 135 fps in demo four, in linux with 24 bit desktop i get 64-65 fps. I read through this thread and changed to 16 bit and got my fps up to 100 fps. Any ideas how I can get the performance up close to windows so i can play enemy territory in linux? Hardware is as follows:

Athlon 2000+ XP
Abit NF7
512 MB ram
Geforce 4 MX 420 (junky, but I at least want close to the same performance as in win2k)

Fast writes enabled, no errors in XF86 logs. I've tried everything I can possibly think of.

Thanks for any help.

oh good reznor.

you got dual boot to compare win2k with RH9 with same hardware. Definitely faulty drivers. RH 9 only got half the framerate win2k. It seems the driver doesn't work with the MX cards properly.
What resolution are you running at? glxgears fps?

800x600 and there is no change in the frame rate with FSAA on, but it drops to around 40 fps at 1024x768, while i get around 70 fps in win2k with the same settings. I don't have glxgears installed right now, I'll go do that now and post later.

here's my glxgears, i just typed glxgears from command line, so i guess it's in the default window with default settings. Desktop is 1024 and 24 bit color.

4122 frames in 5.0 seconds = 824.400 FPS
4539 frames in 5.0 seconds = 907.800 FPS
4540 frames in 5.0 seconds = 908.000 FPS
4541 frames in 5.0 seconds = 908.200 FPS
4538 frames in 5.0 seconds = 907.600 FPS

I'll switch to 16 bit again and see if there's a difference.

Same settings except for 16 bit desktop:

6983 frames in 5.0 seconds = 1396.600 FPS
6983 frames in 5.0 seconds = 1396.600 FPS
6954 frames in 5.0 seconds = 1390.800 FPS
6980 frames in 5.0 seconds = 1396.000 FPS
6984 frames in 5.0 seconds = 1396.800 FPS
6983 frames in 5.0 seconds = 1396.600 FPS
6980 frames in 5.0 seconds = 1396.000 FPS

Kind of ironic that Nvidia put 3dfx out of business partly because of not losing any performance at higher color settings. Must be a bug or something isn't turned on or off by default and we just haven't ran across it yet. I really don't care about glxgears, but the huge discrepancies in Quake3 between win2k and linux performance on the exact same system really bother me. I really want to eliminate any need for windows, but as long as I'm getting 2x the framerate, there's no way I can go exclusively with Linux.

Looking forward to some kind of answer, even if that answer isn't what we want to hear. Thanks for any help that may come.

reznor:

the results are slow for G4 mx at 1024 24bit
if it can't run glxgears fast enough it definitely can't run anything fast with textures and lighting.

yep, there's a problem somewhere, hope they find it soon and give us a fix. This is somewhat aggravating.
