I have Option "AGPFastWrite" "true" in my xorg.conf, and alternatively I did also try to load the nvidia driver with the experimental option NVreg_EnableAGPFW=1 before starting X. But Fast Writes always shows up as Disabled in /proc/.../status (see below). > [EMAIL PROTECTED]:~$ cat /proc/driver/nvidia/agp/host-bridge > Host Bridge: VIA Technologies, Inc.

Maybe the "LE" of my 5700LE restricts the Fast Writes, not sure, need to check... Thanks again. -- Best regards / Mit den besten GrĂ¼ssen Sven Krahn
