Hi Performer's

I've installed OpenGL Performer 3.1 EA under Linux RedHat 9.0 on an E&S
SimFusion 6000 (based on ATI Radeon 9700) system.
The system works fine except of the frame/vsync synchronization.
On starup of perfly, I get the messages below:

The perfly shows FREE_RUN, but achieves only the emulated 60Hz. How can I
force a "true" free run (as fast as possible)?

Thanks,
Hans-Peter
