agg23, I actually don't own a G3 running 10.4.11 at this time (I only recently got a PDQ WS 266, but I'm not sure if I'm going to use it as an 8.6 Classilla test rig or try to XPostFacto Tiger on it), so I couldn't say. I will say that the speed improvements alone are key, and the app is specifically tuned too, so you will probably notice a significant difference. However, a G3 and most low-spec G4s probably won't be able to play video well; even my 1.33GHz iBook G4 had a bit of trouble keeping up occasionally, though the G5 zips right along, natch, so I peg 1.25GHz as probably the minimum to play video reasonably.

PowerPup, glad it's working on your TiBook I daresay that overall you'll find it snappier over 3.6. It's certainly snappier on this quad.
