Blender V 2.35: works ok

GLXgears: works fine I get:
5017 frames in 5.0 seconds = 1003.400 FPS
5379 frames in 5.0 seconds = 1075.800 FPS
5376 frames in 5.0 seconds = 1075.200 FPS

Ok, to install the nvidia driver this is what I did:

all this as root
edited fstab to init3
reboot
login as root
sh NVIDIA driver script
cp -a /dev/nvidia* /etc/udev/devices/
chown root: /etc/udev/devices/nvidia*
Then followed NVIDIA directions for xorg.conf
modprobe nvidia
edited fstab to init5
reboot

here I atach some files so you can see more detail.

Please help, basically I cant run OpenGL games : Tux Racer, TORCS, GL-117

VIA Chipsets have certain issues regarding the AGP port. Entirely resolvable, I'm glad to say. If this is what's causing your problem (and it was the source of my problems) then you need to increase the AGP Driving Value in BIOS Setup. From memory, I think I found 0xDA was the value that worked for me, but it's likely to be card-and-board dependant to a certain degree, so play around with it.

Soluzar, I increased the AGP Driving Value in BIOS Setup by steps of +1 up to FF to no avail.
original value was set up at oxDA

problem persists, please help
