Hello Jon, Thanks for the detailed response. The current implementation of GLX using WGL takes a few shortcuts, basically anything that is drawn with OpenGL isn't composed into the screen, it's just drawn on top of it. I wouldn't want to sound too peevish, as I was quite hap

Lester, Exactly what kind of speedups are you expecting here? AFAIU, the GLX-accelerated XWin will give you speedup only for programs that use the GLX extension, which automatically excludes most standard X clients (e.g., xterm, emacs, etc). For applications not using the GLX extension, the GLX
