Bit of a newbie question :)

Most OpenGL implementations include a fallback software renderer. Obviously, the quality, feature support, and speed of the software renderer varies depending upon the implementation. The Windows implementation of OpenGL is all-around rather crappy, and the software renderer isn't any exception. Other OpenGL implementations that support software rendering, such as Mesa, do a much better job overall.

Yes, it is possible. Windows comes with a software implementation of opengl 1.1. It is a LOT slower than hardware-accelerated openGL though...

edit - Looks like Null and void beat me to it... with a much more complete reply too

Which WA Uni are you attending SoulSkorpion? UWA? Curtin? Edith Cowan? Murdoch?

Just wondering because I will be getting a CS degree at one of them soon...

The Uni machines (well, the ones I''d be using) are all Linux. Anything special I need to know?

If they''re setup properly (with Mesa) they should automatically attempt software emulation; not that it''s going to be as nice as hardware .

Thanks for the help, everyone.

Just to clarify, how slow are we talking in Windows? My app goes from ~90fps to 2fps (if the stars are aligned) in software mode. Is that drastic of a change normal?

Sure, it can be. If you avoid features that software renderers (and the hardware they rely on: primarly the CPU) are notably bad at handling (high frame buffer resolution, higher bit depths, blending, texture filtering, et cetera) it wouldn''t be quite as dramatic.
