NVIDIA 3D: really slow glxgears & game crashes - ARRGHH!

Hi,

I have SuSE 9.1 running on an ASUS A7N8X (2700+ Athlon) with a GeForce4
4600 card. I installed the latest NVIDIA drivers and glxinfo tells me
that direct rendering is enabled. Celestia and 3D games like TuxRacer
run smoothly so the drivers *are* installed BUT:

a. GlxGears gives me ~60FPS which is shockingly crap (far lower than
software rendering). Does anyone know if the following looks correct,
I'm not clear on it (also see end of post):
$ ldd /usr/X11R6/bin/glxgears
linux-gate.so.1 = (0xffffe000)
libGL.so.1 = /usr/lib/libGL.so.1 (0x40031000)
libXext.so.6 = /usr/X11R6/lib/libXext.so.6 (0x40099000)
libX11.so.6 = /usr/X11R6/lib/libX11.so.6 (0x400a8000)
libpthread.so.0 = /lib/tls/libpthread.so.0 (0x401a5000)
libm.so.6 = /lib/tls/libm.so.6 (0x401b5000)
libc.so.6 = /lib/tls/libc.so.6 (0x401d7000)
libGLcore.so.1 = /usr/lib/libGLcore.so.1 (0x402ec000)
libnvidia-tls.so.1 = /usr/lib/tls/libnvidia-tls.so.1 (0x409c4000)
libdl.so.2 = /lib/libdl.so.2 (0x409c6000)
/lib/ld-linux.so.2 = /lib/ld-linux.so.2 (0x40000000)


b. Although Unreal 2004 runs fairly well under 800x600 it doesn't seem
smooth (it doesn't look like particularly low FPS just "oddly jerky").
The worst part however is that it starts locking up after about 30
seconds of play. These lock ups get progressively longer until the
entire system stops responding and I have to hard-reset.

c. I also get S L O W 2D performance within KDE (moving windows about,
etc).

I had in the past tried the SuSE YOU NVIDIA update with a SuSE .RPM but
I wasn't using 3D at the time. I know: why did I bother installing it?
Could there be a freaky conflict between the two drivers? Anyone
experienced these symptoms? Please help, I've Googled till I'm blue in
the face and no answers appear.

Cheers!
Rob

p.s. I enclose the following in case it helps:-


XF86Config is ok:
Section "Device"
BoardName "GeForce4 Ti 4600"
BusID "2:0:0"
Driver "nvidia"
Identifier "Device[0]"
Screen 0
Option "Rotate" "off"
VendorName "NVidia"

The kernel modules are the
$ lsmod | grep -i 'nvidia'
nvidia 4808660 12
nvidia_agp 7708 1
agpgart 30888 2 nvidia_agp


I'm fairly sure that I have the correct drivers and links everywhe
