I have been working with OpenGL on mac, unix, and windows platforms. although i am a mac/unix lover at heart, i am purchasing a new windows laptop and am trying to muddle through some of the configured video cards offered. The machined i want comes with the ATI Mobility M4 3DVideo 4XAGP. Does anyone have experience with this cards OpenGL support, or any ATI cards? Mine has not been too favorable with the Rage ATI set.
