Thanks for the post!

So the only way to solve my problem is to install ATI proprietary driver (fglrx).
That's probably the case, though I don't know for sure how well it'd work with your card and fglrx since I can't test on anything but my HD 5000 series card. It's one of the curses of developing alone. If your card is HD 3000 series, it probably supports the features the game needs. If that's the case, the game should at least start with fglrx. I don't know about performance, though. Lots of stuff is still unoptimized so it might be sluggish.
In the layman terms, you need a graphics card that is marketed as DirectX 10 capable. In OpenGL, that's roughly equivalent to 3.3, which is the version the game checks for at startup. If the driver reports that there's no support for it, you get the error message you got.
Well, I'm not asking you to install fglrx since I have had more than enough headaches with it. If you decide to install it and the game still doesn't start, paste me the output of glxinfo and I should be able to look into it. I don't know if I could make the game work with the open source driver, but with the glxinfo output given by the open source driver, I might be able to try.
KroArtem {l Wrote}:And I didn't find any software requirements on your site (though in README there is information about opengl 3.3) So may be you should add this requirement somewhere on the wiki?
Yeah, that's a good idea. I'll go add it right away.
