We seem to be having issues with low frame-rates with the NVidia GForce
FX cards.
* The latest NVidia kernel module [1] is loaded correctly.
* The NVidia drivers for x.org are loaded correctly:
* DRI is off, as it should be, and
* The OpenGL libraries are correctly installed, the
symbolic-inks are pointing to the correct files, and
"ldd" is reporting correct linking for OpenGL programs.
* X starts and runs without error.
* OpenGL programs run without error.
* The NVidia cards are configured correctly; most importantly
ârefresh on VSyncâ is *O*F*F* (according to "nvidia-configure").
However, despite the correctly running goodness the frame rate for
OpenGL programs ("glxgears" reports â 544 fps) is a lot slower than the
older MX cards ("glxgears" reports â 1,000 fps). Other things to note:
* The poor performance is with both 4x and 8x AGP slots,
* The video RAM that is reported by the system is correct,
* All parts of the system (including HAL, the PCI bus, and the
drivers) are correctly identifying the cards, and
* After doing a Google it appears that the problem is distribution
neutral.
Does anyone have any ideas about what the problem may be?

System Summary

Some responses to typical replies.
1. âYou should have used Gentoo/Debian/SuSE/Mandrake/FreeBSD/ââ
You are not being helpful. As I said before, the problem seems
to be common to all distributions.
2. âYou should have used ATI cards rather than NVidia, which suxâ
You are not being helpful. We have the hardware, we need to make
it work.
3. â"glxgears" is not a performance measurement toolâ
I know, but it nicely shows the problem.
