Bug 66944 – Poor OpenGL performance using nvidia-kernel-1.0.6111-r2

• Status: RESOLVED NEEDINFO
• Product: Gentoo Linux

[Description Bharath Ramesh 2004-10-09 23:20:06 UTC]

I have new Dell Inspiron 8600. I am using gentoo-dev-sources-2.6.8-r7. I get very poor performance when using any GL. When I run glxgears I get 690 FPS on an average. I am attaching my xorg.conf. I havent couldnt get 1.5336 build to work at all, Xorg wouldnt start. Any help on this is appreciated.

Created attachment 41439 [details]
xorg.conf that I am using

Attaching my xorg.conf for the bug

First can you attach your configs as plain/text for future reference.

Im not exactly sure what to say here in regards to the bug, like a Go6650 is not exactly a powerful card... 690fps is probably accuratish.... 

What sort of GL issues are you experiencing? 
Try adding the following to /etc/modules.d/nvidia
  options nvidia NVreg_EnableAGPSBA=1 NVreg_EnableAGPFW=1

I enabled both SBA and FastWrite by uncommenting the options line for nvidia in /etc/modules.d/nvidia. No improvement in performance. If I run any GL application say the screensaver I use GLMatrix and turn on the framerate option, I get something like 4-5 frames a second on an average. This card gives a framerate of around 35-40 on an average in windows. I am not able to understand why I get low performance in linux.

I did more hacking around, when I use color depth as 16 I get good GL performance but when I use 24bit Color depth then the GL performance is really bad. Not sure why this is happening.

[Comment 5 Andrew Bevitt 2004-11-09 17:40:37 UTC]

Does your card actually say it supports 24bit colour modes?

[Comment 6 Bharath Ramesh 2004-11-09 17:46:46 UTC]

The card does support 24bit Color depth. I upgraded to the new drivers 1.0.6229 the glxgear performance has improved but the GL performance is still the same.

[Comment 7 STefan 2004-12-25 14:19:58 UTC]

Of course in depth 24 mode compared to 16 the card is much slower, it has to do much more work, the performance of 690fps is ok for that card, so I do not see any bug or error here.

[Comment 8 Andrew Bevitt 2005-01-08 06:39:46 UTC]

If the speed changes over colour depth changes then there is little we can do but wait for the drivers to be updated...

[Comment 9 Joshua Baergen (RETIRED) 2005-11-20 12:15:29 UTC]

Is this fixed in any of the newer versions of the drivers?

[Comment 10 Joshua Baergen (RETIRED) 2005-11-20 12:15:47 UTC]

Re-assigning to -drivers.

[Comment 11 Bharath Ramesh 2005-11-20 16:06:02 UTC]

I am sorry I dont have the hardware any more to test it anymore.

[Comment 12 Joshua Baergen (RETIRED) 2005-11-23 21:00:11 UTC]

Alrighty

Anyone else who comes across this issue should feel free to re-open this bug.
