Compiz doesn't detect monitor's refresh rate correctly

[Pevzi]

Compiz detects monitor's refresh rate incorrectly, so the performance is very low with default settings.
My monitor works at 60 Hz (or 60.02 as the NVidia Settings tool says), when Compiz choose 50 Hz by default. Also when synchronization with Vblank is enabled, tearing disappears in some cases, but sometimes lags just get more terrible.

Monitor: ViewSonic VA702
