If I remember correctly, the RM4 has 4 Mb of Texture memory on it. The RM5
has 16 Mb.

Beside the difference in texture memory, I don't think there's a difference
in performance between the two boards.

The new machine you received has only two raster managers. I looked in the MCO
Ownwer's guide and found that with 3++at++960x680_60, you'll get only a small
pixel depth -- or no antialiasing.
Your options are:
1) Reduce the resolution, or
2) Increase the number of RMs to 4.
