Do you find the interface slow? Not really. And I am on a Pentium3 800Mhz. But, I have 1Gb of RAM and I suspect that RAM amount is much more important than CPU speed for many things. > Do you find the program taking a pretty long time to load? It takes exactly 41 seconds to load on my Win2000 computer. So I rate it "normal". > Do you find the rendering in Firefly sometimes cutting the head off Victoria, Mike, and even that funky looking Judy? Not yet. I got some weird result with the smoothing enabled, but after I turned it off it seems to work perfectly (except with the transmap reflections that is). > Do you get those c exception errors? No, never got any. > Do you find the FF rendering a bit too time intensive ??? All high quality renderers are time intensive, unless you have a superpowerful computer. There are some few exceptions (like Cinema4D renderer), but in most cases, quality is slow. But, I think that the draft more or P4 renderer are good enough for standard "everyday" renderings unless you have specific needs about reflections etc. Then, I have (for work reason) two computers, so I usually move to the second computer while the first one is rendering). > do you get render lockups? Never got any yet. >Does your library take a nap while it loads different >subdirectories? No... Library switching seems to be much faster after the patch. don't know if it's just my impression.
