Banshee & X-Plane

I found X-Plane the other day which requires OpenGL. I have a Banshee PCI 16MB card as primary and an ATI Xpert@Play98 as secondary. I have downloaded all the latest drivers for the Banshee card from all the locations I can find. Unfortunately, X-Plane is incredibly ssslllloooowww (approx. 1, yes ONE, frame per second on a 700MHz Thunderbird w/128M & 15GB 7200RPM HD). While I’ve heard the Banshee is slow with OpenGL, I don’t think it should be this slow.

I also saw some mention of renaming 3dfxvgl.dll to opengl.dll, but there is no 3dfxvgl.dll on the system.

Thoughts?

Thanks in advance,
