Heya... I was just running through tutorial 11 (the flag wavey one), & found it to be unbelievably slow on my G400 (like, 1 frame every 3 seconds slow). If anyone else is having this problem, you might like to try removing the glPolygonMode( GL_FRONT, GL_LINE ); // Front Face Is Drawn With Lines line....works for me. Of course, if anyone has any suggestions on fixing this without removing the line drawing mode, I''d be interested... Cheers Cat

For me tutorial 11 doesn''t work in fullscreen with my ICD driver. Just in windowed mode with microsofts driver. In windowed mode all opengl apps are SLOW.

I''ll see if that code change will fix it. Thanks.

wow. That worked. Now i''m able to run it with my ICD driver and get about 20-30 fps.

Thanks.
