We handle card discrepancies like texture size, number of units etc, by
querying the the cards cabalilties and setting up our limits in our
programs from them.
( now some dang cards can tell out right lies about what they support
and drop to s/w mode at times but thats another story )

Do you think that changing the shadow texture size will have any
affect here? I have noticed a somewhat similar failure of ShadowMap
when I have a very large mesh file, and decreasing the shadow texture
size seems to fix that.
Oh, possibly. The GeForce 5's might have had a smaller max texture
size, too. It's been a while, so I don't remember the numbers exactly.
In general, though, they had tighter limits than the modern cards.
