Quote - Nomuse, are you using Open GL or the Eovia preview? I've found that switching between them will sometimes improve performance based upon the mesh. I did note some performance gains when I updated to OS 10.4.6 - there was a Nvida driver update with that if you're usin their hardward.

Both and all. Tried with OpenGL, with display lists on or off, and with the Eovia interactive renderer. Installed the latest driver fresh off their site after confirming Apple also listed it on their Tiger support pages, and tried all three options again. As far as I could tell there was little change. This does not appear to be a display issue per se...what creates the huge slowdowns is trying to actually insert a vert, move a line, or do a weld. When I do that the program lags far behind. I could literally make a "cut" in a mesh by using only my nose on the mouse and keyboard, and still keep ahead of the program. My guess at this point is hardware, but based on my specs and assuming no optimization, the fastest last-gen G5 will still show a slight lag if I start working too quickly. Still, that would be better than what I've got now. > Quote - Hope you can get that worked out. Is P5 still not working on your system?

Using the via-classic memory hack I was able to get P5 running for short bursts. According to e frontier it isn't supposed to be work at all and they don't support it. P6 works quite smoothly, tho, and if all I was doing was slapping 3d-party temples and swords together I'd be quite happy with it. All in all, Tiger has cost me over two weeks of productivity already, and is looking to cost more weeks on top of that. In return I've got....I'm not sure what. Sure, it runs basic services faster and I like the layout, but...
