There are 2 options in GUI with Sync To Vblank. First is in "Opengl Settings" and the second one is "X Server Xvideo Settings".
In the new driver the second option in the "X Server Xvide Settings" is gone, but it seems to be enabled cause performance level goes to 2 for any small things I do like opening a web browser etc.
I've tried you solution and it didn't worked.
