  What performance issues? Me and other people tested this on multiple machines without noticing problems. You have a way to trigger the performance problems? Certain apps, effects?
  
  Not syncing to vblank is not per se a performance issue as in lower framerate. It just means the latency is not optimized. On current master we do this with maximal possible latency of one frame all the time btw.
