[Mesa-users] Intel poor performance in simple OpenGL program

[Carlos Eduardo Rodrigues Diógenes]

Hi,

I run the same program in Windows with the latest drivers installed
and the performance, visually, is practically the same. So, I can't
uses lights with this card or the program that I'm running isn't using
my card well, what I doubt.

Best regards,
Carlos.
