I second the suggestion to use OpenJKDF2 (link in the post above). I tested it out just now and found that the game runs better and more smoothly with it than every other solution, including dgVoodoo. Also, it's the only solution that I know of that lets you adjust the FOV, which is huge.

It's in beta, but it seems to work very well. Just download win64-debug.zip, extract it to your game folder, run openjkdf2.exe and then go into Setup and adjust settings.

Tip: The graphics felt smoother to me with OpenJKDF2's frame limiter set on unlimited and leting my GPU software's frame limiter do the work, rather than setting the game's limiter to the same value, so I recommend just leaving it on unlimited (far left of the slider) if you already have a system-wide frame limit set.
