Hi,

To be clear, do you have VMGL running?  And you're only getting ~35 FPS?

For me, using VMGL doubles the performance of glxgears on two different 
machines.  As well, I'm using the "Enemy Territory" demos the author 
used and they are usable with VMGL but still jumpy.

How do you use VMGL?  Do you use VNC or do you have SDL working some how?

Thanks,
Cam
