Yep, got the same problem here: some of my effects are really toooooo slow. For examples, I wanted to put a scrolltext in the bottom for all the demo, like in oldschool ones. But for the plasma and tunnel effect, some gasp appears, and the scroll stops being smooth...
My wireline part was using a "blur" effect but was also too slow. I used some oldtime trick like buffering the old coords in several arrays, but at the end, it was really not so good for me. So I managed to change it, it will be participating effect

Hooo just a question, I made at first a improved version of the tutorial effect, should I included it?
