What's up ya'lls ?!
Have problem with glxgears displaying FPS slower that you should get ?
I have it... but !
There's a REALLY easy solution for ya !
Yup, change bit depth to 16 if you have 24  (/etc/X11/xorg.conf)
Before that i had 740 FPS, now it's 1400. On GF2... I think it's good.
My system:
Athlon XP 2600+@2800+ Barton

Huhuhu... I forgot to say you should also add some lines to /etc/X11/xorg.conf:
| Code: | # **********************************************************************
# Graphics device section
# **********************************************************************
# Device configured by xorgconfig:
Section "Device"
Identifier "GeForce 2 MX400"
Driver "nvidia"
Option "NoLogo" "true"
Option "AGPMode" "4"
Option "AGPFastWrite" "true"
Option "EnablePageFlip" "true"
#VideoRam 32768
# Insert Clocks lines here if appropriate
EndSection |

As always, make backups of your config files before you touch them.
This is especially true when changing your AGP bus settings such as Fast Writes and Side-Band-Addressing.
Also especially with the above 2 options, be prepared for hard-lockups if you have an old motherboard. |

I added those to my X config file but the X logs show
| Code: | (II) Loading extension NV-CONTROL
(WW) NVIDIA(0): Option "AGPMode" is not used
(WW) NVIDIA(0): Option "AGPFastWrite" is not used
(WW) NVIDIA(0): Option "EnablePageFlip" is not used |
