> The reason that JSUI is slow is that it uses a software based > OpenGL renderer Aha! *NOW* i understand why JSUI is slow. ;-) It has nothing to do with the FSAA per-say.. this software-based rendering is of course going to be slow. Surely it might be eventually possible to drop-in a more efficient renderer that takes advantage of the operating system facilities for OpenGL? (Maybe this is planned, sorry I haven't read about the upcoming version yet..) By the way I don't share Zola's opinion here. I think JavaScript is actually quite a decent language. As for speed of execution, I pretty much always expect interpreted languages to be slow and never expect to use them in time-critical tasks. This is what C is for. I never did understand why the JSUI stuff seemed slower than need be, but I didn't realized it was completely software rendered... (thus.. defeating the purpose of using OpenGL?? Though I'm sure it made it easier to implement.) Steve
