I can also confirm .drirc gets ignored but env vblank_mode works. To disable vsync completely you currently (and before) need a DDX hack along with vblank_mode=0. With this patch interestingly glxgears goes from ~1400 fps to ~2100 fps and Quake 2 can run uncapped. What is the real solution and why is this patch needed in DDX?
