Well i can add that again to Ctrlr no problem, but i doubt it will increase the performance of drawing itself. It’s how you draw with JUCE, how much and what you repaint. Did you look at the Rendering DEMO and compared it’s performance with your components ? I don’t know how much overhead is happening in luabind i wanted to try to replace lua with luaJIT that is faster, but i don’t know how well it will work with luabind.
Maybe you could provide some test cases for drawing i could try and experiment with, i could try to do some tests with those new features and see if they will help before i’ll do a full implementation. There are 3 things i can test quickly (opengl, luaJIT, and your code).
I wouldn’t put too much faith in opengl and luaJIT, they will give us some performance bumps but i doubt they will be significant. Worth a try anyway.
