Hi Babrook. I got the same problem, so I may give you some clues.
I have a Voodoo3 3000 16MB AGP card that worked fine for me (till I find this game

). If I try to run the game in OpenGL mode, I get a white screen (what should be the splash screen). Few seconds later, three buttons appear and, if you are running fullscreen, the mouse pointer is gone.
I found (in my case) that the GLide from 3DFx is not compliant with the OpenGL plugins of the game. So, I managed to run the game in Software (Safe) mode but, in my 1 GHz Athlon with 256 RAM its is toooo slow (about 2 to 4 fps). Wandering around the forum, all the advice I got is to chege my video card. Thus, my GF4 is arriving this week. :]
I recommend you to do the same, and get more RAM too. The FAQs talk about 300+ RAM to run properly.
Nevertheless, you can always check what video card you have in the \"System\" Icon in the control panel. There, click the \"configuration Manager\" and browse the tree to find yor Video Adapter\'s name.
Good Luck. :tup:
