Hey,

does anybody have experience with it ? I've set it up 4 times on 4 different machines. And there was always problems with slow rendering ( for instance : scrolling pages in browser is not fluent). But there always was something that finally made it work perfectly...

I remember that one time this option helped, but not now

Option "RenderAccel" "1"

Nvidia geforce 8400GS or Zotac geforce 9500GT

Monitors connected via dvi and hdmi connectors

proper nvidia driver installed
