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 On Fri, Mar 11, 2011 at 03:02, Andy Colson <[email protected]> wrote: > On 03/10/2011 07:16 PM, Andy Colson wrote: >> >> On 03/09/2011 08:47 PM, Daniel Morissette wrote: >>> >>> The MapServer Team is pleased to announce the release of MapServer >>> 6.0.0-beta1.
