I have a GEForce 3 and it doesn't crash, refreshes okay, but is just too slow to use. I don't like to disable the background thread. So I use wireframe. I'm still trying to figure out the right slider settings to use so I can see what I'm doing. OpenGl works fine in Bryce for me, but it also gets sluggish with a lot in the scene so I just use wireframe there too. There's nothing wrong with using wireframe but area rendering becomes sooo important for checking what you've done in the scene and I find that a bit of a hassle in Vue. Still learning though.
