PCSX2 very slow in Linux

Hi!

​

I'm using Calculate Linux (Gentoo-based) and using version 1.6.0 of PCSX2. Every time I want to run a game, everything is fine except at some point.

Tried here with Mortal Kombat Armageddon and the result is seen in this video.

No matter the tweak I do, I tried everything, changing settings and the result is the same.

This doesn't happen in Windows (with DirectX or OpenGL, tried with the same game).

​

I have an i5 Sandybridge, 8 GB RAM, Intel Graphics and Nvidia GT540M.

Thanks.
