wires

Hye there, thanks for making this.. I missed this game so much! I'm using win7 x64 with radeon 5850 videocard... it ran fine but it flickers a lot.. at first it blinking.. after I add "-f" at the end of target of the shortcut (like in the troubleshooting advice) it flickers... is there something I can do to eliminate it.. If anyone know how to change resolution or something.. that'd be helpful.. maybe it's just because I use 1080p monitor at 60Hz?? Thanks in forward..
