... but this misses the point. Irrespective of whether modern 3d card
acceleration options are compatible with raytracing or not, povray is
unlikely to support them if it requires custom code.

On the other hand, if the 3d card automatically took over the calculation
from the main CPU when appropriate....

That said, given what I understand of POV and 3d cards, unless 3d cards were
suitable for involvement in *any* intensive CPU activity, then I fail to see
why they would be of use.

Povray, after all, is about creating a file from a series of calculations -
the display of the image is not part of povray's job.
