You can't separate video performance from IDL performance,
particularly with high-end stuff, because RSI probably implements
their graphics operations for maximum compatibility rather than
maximum performance-- implying that the gee-whiz stuff (such as
programmable vertex and pixel shaders, static vertex arrays, etc.) in
your 3DLabs card won't be used. If you really, really, really need the
high performance you'll probably have to implement it by hand, via a
CALL_EXTERNAL routine that creates its own OpenGL context.
