Steam output

Game runs, but there are problems with:

1. Resolution — few parts of game are hidden. Xrandr says I use 1920x1080 and in game I have set the same resolution and aspect ratio to 16:9,
2. Brightness — game is too bright until I change in-game conf to anything — it fixes the problem until next time I start the game,
3. Overall performance — there are a lag though on the same machine with same in-game conf, but Windows 7, it runs smoothly;

What can I do to fix mentioned problems?

Re: Performance problems running DotA 2 from Steam

I can only speak for #3: don't expect parity performance with the GL renderer and the DX renderer in dota2 yet. They need to do a few big optimization runs for d2 on GL.

As for #1 and #2, I don't know, on NVIDIA here and have no problems like that. Perf is poor, but I do have a rather poor laptop card.
