Should be fixed in: 0a7803cbaca13033d9ed31ef33f59efa913fbfce
For me using rv670 it doesn't work from .drirc eg.
<driconf> <device screen="0" driver="r600"> <application name="all"> <option name="force_s3tc_enable" value="false" /> <option name="disable_s3tc" value="true" /> <option name="vblank_mode" value="0"/> </application> </device> </driconf>
It does work as an env so vblank_mode=0 ./gears works - but I still get wait for vline sync which means that fullscreen games or gears maximised gets capped to refresh.
