--- Comment #27 from Jonas jojonintendo@tutanota.com --- I just retried Portal 2, Team Fortress 2 and L4D2, and it seems that when games launch I get a big hang (which looks like it's going to crash), but then it restores itself and works great. When I talk about "dpm that seems to fail" I mean that when the GPU must use more power, the game stutters. But at least it's working, I just tried to make it crash without success. I'm attaching dmesg and xorg, because I think there are some differences.
As far as I'm concerned, it seems to be working pretty good. I'm looking forward to see if someone can confirm this.
