You never do...

Just so we're on the same page, your Wildcat will only show it's teeth while
using hardware (openGL) rendering in object graphics. Matt's comment that
RSI designs the OG rendering system for maximum compatibility is right on.
Although I have no inside knowledge I would assume they use few if any GL
extensions so many of the features of mondern 3d display adapters go unused.
That being said, it doesn't mean you can't push a lot of pixels. The
Wildcat4 is an impressive card on paper. It should do quite well in IDL.

Performance depends a lot on what you are doing. Can you describe what you
are trying to do? How are you measuring performance?

I don't think that this is a 32/64 bit issue as you are unlikely bumping
into the address limitations of the PC. In general, viz applications are
bottlenecked at the display adapter (depending on the vertex count/window
size).

What sort of acoustics?
