The cursor moves ok, but the game doesn't respond to the movements and clicks immediately. (for example:i move the mouse over the menu rapidly for several seconds and then press the button. The button pushes only after several seconds - like with low cycle setting). But the game doesn't slow down and the sound runs ok. The lag time depends only on the amount of movements. (no movements - no lag on clicks)
(attach a video captured with fraps)

When using a 100Hz mouse the lag is probably small so it can't be noticed. But with a 500Hz mouse it can be 10 seconds (and more(depends on the amount of movements)).

This happens only in "Into the Void" (ver 2.0.0). Other games (even more resourse demanding) run ok.

I tried different video modes, core emulation, mouse sensivity, set up cycles manually - nothing helped.
