Why is glxgears so slow on new install?



I am _presuming_ that glxgears being much slower indicates something
wrong.

I am using Slackware 10.2 newly installed after formatting everything
except /home which is on a separate partition. There are no hardware
changes.

Running glxgears on the new machine using my very old xorg.conf (used
to be xf86config) glxgears give 8 times the speed (1600 fps)
as on a new xorg.conf (196 fps) created with xorgconfig and I cannot
understand why.

The monitor, graphics card, computer motherboard are exactly the same.

The settings in the two xorg.conf files seem to be the same. I
printed them out and compared the settings for Input Device - Mouse,
Input Device - Keyboard, Monitor Section and Graphics Device Section
and they appear to have the same information. For example, HorizSync,
VertRefresh, Graphics Driver "ati" and other settings that could make
a difference. I've also switched the DefaultDepth around from 24 to
16 and back.

My hardware is a Samsung SyncMaster 910v monitor and ATI Radeon 7500
QW graphics board.

The only thing I can think of is that something may have changed in X
itself but I don't know how to go about troubleshooting that.

Any advice would be appreciated.
