--- Comment #8 from Artivision artivision3@gmail.com --- Officially the Dgpu works fine at power_level_2 at 400mhz, if i force "battery" level. There is no way to test power_level_3. Finally, before or after the game is start, if i force "performance", terminal shows power_level_4 and 850mhz for only two seconds and everything hangs.
