Games that i tested today and that work:

Skyrim (needs dll-overrides)
Gothic III

So, it is related to optimus. My nvidia card (GT525M) works fine (with debumblebee), and intel works fine too.

Why Linux tries to get MUX INFO if I have MUX-less Optimus implementation?

OCR engines: Tesseract, cuneiform. Others are English-only, so I did not used them.

GUI: for tesseract - FeedReeader, for cuneiform - YAGF and other.

But these OCRs are worse than FineReader, so if you have bought FineReader, you can use wine to use it (wine does not support scanning, so you need scan to pdf with xsane and OCR this pdf with FineReader, and don't save results to .doc - OpenOffice have problems with docs generated by FineReader).

Dec 30 07:55:56 franchuk-r kernel: [ 9.023258] [drm:intel_dsm_platform_mux_info] *ERROR* MUX INFO call failed

What it means?

Hardware: Intel HD3000 (integrated with Core i5-2410M).

Linux: 3.1

Games that I played with wine and that works fine:

Many alawar games (some bugs with cyrillic locales)
TES V Skyrim (needs dances around fire with winetricks)
Assassin's Creed (Dx10 version does not work, only Dx9)
Heroes of Might and Magic III, IV, V
NFS II SE, III Hot Pursuit, Hot Pursuit II, Underground II, Undercover
Gothic, Gothic II
Half-Life, Half-Life 2
Team Fortress Classic
Counter-Strike 1.5, 1.6, Condition Zero, Source
S.T.A.L.K.E.R: Shadow of Chernobyl ("white sky" bug with dynamic lighting)
Warcraft III
Soldier of Fortune 2
Medal of honor
Revolt (works only version that patched to support win7)
Quake 3 and most of games based on id Tech 3
Doom 3 and most of games based on id Tech 4
Age of Empires II with mods
Age of Empires III with mods
GTA 3
GTA Vice City

And many many other. The most of games which I tried.

Games that don't work with wine:

GTA IV
NFS Shift

Many other games do not work for me because I am too lazy to find way to bypass copy protections.

GCC is CLI application, not gui.
