Slow is relative as G4s go from 0.45 to 1.8GHz and even some ultrarare 2.0.

For GFX anything that isn’t a 9000 will be slow for sure.

The new TinyGL does/should provide 3D support for all these cards, just no legacy W3D. Latest beta also omitted t3D for R600 but that should be fixed in 2 more weeks…..
