You can also disable tear-free buffer swaps by adding: Option "SwapbuffersWait" "FALSE" to the device section of your xorg.conf. That coupled with vblank_mode=0 should give you maximum framerates at the expense of tearing. Alex -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".
