wireframe is slower?
Author
do somebody know why glPolygonMode(GL_FRONT_AND_BACK, GL_LINE); is slower thar glPolygonMode(GL_FRONT_AND_BACK, GL_FILL);?
The driver has to convert everything to lines. If you sent everything as lines to begin with my guess is that it would be faster.
becorse real lines arent supported in most cards, so its really thin quads.. however, it should be faster in fillrate so thats not your limit yet 
On my Radeon DDR using glPolygonMode(..., GL_LINES) kills the fps (down to ~25%) but on my Geforce2 MX there is no difference in fps... strange.

afaik lines support on most "consumer" hardware is disabled by the driver to make people who want to run those cad progs with many wireframe models buy their "premium" cards
but thats just my .2€
