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

[thomas bonfort]

Andy,
yes a (beefy) video card is needed or at least wanted, as you want to
offset the calculations to the GPU. If one isn't present, you're going
to fall back to a software opengl implementation which will be orders
of magnitude slower than what AGG is going to take.

cc-ing Toby if he wants to comment further on this.

regards,
thomas
