[ Closed ] Client "hangs" suddenly in game, Windows 8.1

[THIS PROBLEM ISALREADY SOLVED]
Hello, dear communitee,

I really love the game, but can't enjoy it for 2 months: 2 months ago I installed windows 8.1 instead 7. Since that time, I regretted much.

The problem, is that Teeworlds client "hangs" suddenly in 1-25 minutes after entering the server. It looks like a scrennshot or  paused game.
Of course, I tryed to solve the problem myself,and I found 2 ways of terrible playing:
1) Use Nvidia GeForce to run teeworlds. Yes, I run Teeworlds with video processor GeForce GT 630, and all I get is not more than 50 fps and slow input (game responses my key presses in 0.1-3seconds)
2) Use integrated video card(just disable Nvidia utility)<-- that's how all the people play, and I played on Windows 7 without problems. But actually in this way the client hangs.

Does anybody experienced the same situation or has any ideas what to do?

P.S. On windows 7x64 everything worked fine. My Windows 8.1 is 64bit and teeworlds client is win32. (I can't build win64, only win32)

[SOLUTION]:
1. Built the newest bam as win32.
2. Built DDRace client with it, used VC (VS 11.0)
Now it works fine. By the way, I did the same with vanilla client, and it still hangs. So, I gonna use DDRace client untill Teeworlds SDL 2.0 release.
