A few problems.
Could you guys help me with this problems?

1) Odd mouse feel, nearly mouse lag.
2) Stuttering... it isn't fixed yet?
3) Directional audio. If you point directly where the guy is, you don't hear what he says, same for pointing in the opposite direction.
4) It flasehs randomly light black screens for 1/4 of second.

So?

Thanks anyway.
