PS: For Fallout 3 those registry settings should be (or similar): "VideoDescription"="NVIDIA GeForce 9600 GT" "VideoDriver"="nv4_disp.dll"
We have a display driver database in wined3d that specifies the driver version to report. We could include this information there instead adding a new registry key.
"nv4_disp.dll" obviously makes problems. Our display driver is called "winex11.drv", or arguably for d3d "wined3d.dll"
