Slow vpdau with GeForce GT 520 (GF119)
 
Hi,

Mainboard Asus P8P67
Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz
GeForce GT 520
Kernel: 2.6.38.8-31.fc15.x86_64
system: Fedora 15 x86_64
Nvidia driver: 260.19.21-2
xorg-x11-server: 1.10.2-1.fc15

I don't know why but when i run qvdpautest on my machine, the H264 DECODING (1920x1080):
only shows 4 frames/s compared to other users who have the same graphic card.

The same results with driver version 270.41.06, 270.41.19, 275.09, 275.09.04,

Code:

[root@fc15 tmp]# qvdpautest

Is this only a problem with Fedora or the NVidia driver ?
