Hi Mike !

Another potential problem:

Do you use pf2.4 multi-processed (pf2.3 is always single-processed) ?
Do you modify the contents of your geometry (lines ?) on the fly ?

If the answer is yes on both, you should take a look at fluxed geosets and
pfFlux in general.

Moved to Performer 2.4.2, with NO change of nvidia driver, and now Performer seems unable to draw the blended overlay shapes and cyclic lines without them breaking up randomly (as though some of the triangles making up the circles and some of the lines are being clipped out - weird). Any ideas?
