--- Comment #27 from Peter Petky ptg76@ukr.net 2013-02-20 14:34:01 CST --- Today there was a software optimization an update to version 2.0.4. So, I turned off almost all visual effects of KDE and rebooted my PC. After that I ran the game: the music, sound effects are clear, the characters' speech understandable. And yes, I had to manually modify Variables.txt to reduce the screen resolution to 1024x768.
height=768 width=1024
It's a little slow (maybe because my video card is integrated to motherboard), but playable. P.S.: wine 1.5.24 (with virtual desktop emulation 1024x768), StarCraft II 2.0.4 (Universal - 2.0.4.24944)
