DOTA 2 - FPS DROPS ON DEBIAN - G310M GRAPHIC CARD.

Hey there, whats up?

I used to play Dota 2 on Windows 8.1 with good FPS (between 35 ~ 45 FPS; but than I changed to Debian Jessie (I cant have Windows no more, its my work machine and I cant use Windows) and started to have several problems with FPS drops.

The notebook is a Samsung R480:
i3 350M - 2.26Ghz
4GB Ram;
Geforce G310M; using 314.02 drivers on Linux.

Every time I try to play, i have a big FPS drop in hero choose, and when I enter the map;
if I run the terminal “CTRL + ALT + F1” and back to GDU “CTRL + ALT + F7” I can solve the fps problems for a time, but some minutes ago the problem starts again.

Someone know how to help me?I’m not in the machine right now, thats why I didn’t posted the nvidia logs.

I’m running it on native steam for Linux, not on wine, btw.
