> According to comments in bug 28771 a the xorg ddx is hardcoded to wait for > vsync That's not true anymore, the vline waits (not vsync, that can be controlled via driconf) can be disabled with Option "SwapbuffersWait" "off". > This should be runtime configurable, preferably per-application like dri. That would require some xserver dri2 changes first, to allow the driver to tell the different cases apart. There's been some discussion about this on the xorg-devel list, started by Chris Wilson. Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases. |
