wine users - Jun 2011 - Need help with unreal tournament

I installed Unreal Tournament '99 and at first it was going too fast so I
set the frame rate limit to 60 and swap interval to 1 in UnrealTournament.ini.

I still have one problem. The game stutters. Every 1 or 2 seconds it stops and
skips that part completely making it unplayable. I even downloaded the new
OpenGL engine and I still have the problem.

Please help.
