Thanks for the pointer. I hadn't noticed that.
However, as the
docs mention, WINE does not monitor its X11 Input event loop. So the
CTRL+SHIFT+F9 function does nothing. (Or if it does something, I didn't
notice because WINE insists on being in the foreground and will cover up
everything else.)
I looked around the source for how the key shortcut
was implemented and figured out how it calls vglconfig.
I hacked
around on a copy of vglconfig and came up with a utility that will allow
me to set the FPS of the WINE instance from the command line. It only
needs the SHM ID and the new FPS value passed to it. It doesn't require
any X11 display.
I've attached a patch that adds this utility to the
2.3.1 version of VirtualGL.
Any comments are welcome. :)

wondering if it would be possible to change the VGL_FPS limiter after
vglrun has been launched? If it isn't possible currently, what does
everyone think would be the best way of implementing this? The linux
kernel does this beautifully by allowing values to be written into
various files in the /proc/sys and /sys file systems. -- Thanks, Dyweni
