Re: what are the trade-offs of the opengl driver?
I have tested this on my 8800GTS and in addition to the two extensions mentioned above, I also have GL_ARB_texture_rg there. So it seems as if the performance improvements in wine are limited to GF>=8.
Are the other extensions also needed somewhere?
BTW: Is there a glxinfo version that supports OpenGL 3.0? At least the version I have only seems to know OpenGL up to 2.1 .
