[mapserver-users] MapServer 6.0.0-beta1 release - Please test! (OpenGL)

[Toby Rahilly]

Hi Andy, Thomas,

Yes OpenGL requires a good video card to be worth while. A poor
quality video card will not only result in bad performance, but low
quality renderings.

That said, it shouldn't be crashing, and I'll take a look at the
dependency on X.

Cheers,
Toby
