If they don't haven't we just found a driver bug? Assuming you're
testing on cards with the same capabilities (you would have to record
what extensions should correspond to what results) I don't see why the
output shouldn't be the same. As long as you keep the tests simple so
that they don't try to do anything like dynamically adjusting detail
based on load, and you do the tests with either the same
aliasing/filtering or none, I would think results would have to be the
same across cards in order for them to be considered OpenGL compliant.
