I seem to be able to run OpenGL screensavers without crashes.
Yep, I though so. I've made them run for a whole night whithout crashing.
But suddenly as I was watching a film (Requiem for a dream, ironically),
the screensaver started and some time later -> FREEZE.
Tomorrow, I'll get the GeForce2 from a friend of mine , and I'll test that card.
