Just to post for future reference that it is not advisable to use WickedGL with Quantum3D's drivers.  Although this may not apply to all cards or operating systems it is my experience with Windows 98 and an Obsidian2 X-24 and an Obsidian2 200SBi that Quantum3D's drivers conflict with WickedGL.  The results are either really psychedelic 8) or else the game won't run at all.

3dfx's minigls work fine however.  :)
