Re: [Visualpython-users] [Q] Running VPython on IBM ThinkPad (fwd)

[William C. <wc...@an...>]

   In my experience, I have had trouble  S3's Savage 3's and Virges doing 
OpenGL rendering. Though this is a SavageMX, it may be based off of the 
same chipset as one of those two (I've never personally worked with one). 
As professor Sherwood said, I had to bypass hardware and go straight to 
software rendering. D3D never had any problems as far as I could tell, but 
OpenGL was always spotty.
   Also, though this may be a bit of an obvious answer, try checking out 
some alternate drivers (a la driverguide.com, windrivers.com, etc) and 
seeing if there are any drivers for your card there -- if others have had 
the same problem with OpenGL, there may be some patches or fixes.
