Software Rendering far too slow

I am doing some work with OpenGL on a computer that has no OpenGL drivers. It still works in software mode, but very slowly. Is there anything I can do to speed it up a little. I only have 10 quads on the screen and I''m getting about .8 fps Jason Mickela ICQ : 873518 E-Mail: jmickela@sbcglobal.net ------------------------------ "Evil attacks from all sides but the greatest evil attacks from within."

Have you colored polygons?

I''m not quite sure I know what you mean.
My quads are all red. Just to clarify, they are all different
objects, not pieces of one object so a polygon wont help.

Hmmm... thats a tough problem to solve... HOLD IT! No its not. Software rendering is the slowest thing since witnessing Hillary Clinton''s thought process. It''d take a damn fast computer to display software rendering at a decent FPS (even if there is nothing on-screen). Sooooo, thats solves that.

Wow, I don''t really like that "solution". With a name like "ProSavage" you would think this card would support OpenGL.
Not very "Savage" more like "ScaredLittleGirl". Damn work computers, worst part is the next batch of computers coming in will ALL have GeForce 2''s in them. I may have to do a little switcharoo.

Writing a software renderer might be a bit extreme, depending on what you are doing.

Try this:
1) turn off goraud shading (use GL_FLAT)
2) turn off lighting
3) turn off texture mapping
4) use smaller window
5) use the old SGI OpenGL implementation (software only, and its faster than MS)

I did manage to get about 30 fps on a pentium 100 with a small window, about 16000 polygons and lighting, but none of the others.

That''s when I decided to buy a new computer
