The application of "every frame perfect" to the mouse pointer ranges from neutral to actively harmful. It causes roughly 1 frame of delay, which can be enough to bump the display-eye-hand-mouse loop out of whack (this seems to be different from person to person). It also causes pointer stutter when the system is under load side the pointer can't be independently updated.
+1... every frame perfect is less important than lag (ie something should happen at next frame after user action).
Pointer should be async with the rest of desktop anyway, unless the system is broken.
