Processing using way too much CPU?

JackH

Hello everyone! I am developing a simple Chess website and have gotten relatively far but for some reason, the 'Safari Web Content' is using over 100% of my CPU. It also makes my click events extremely delayed.

how do we optimise code we cannot see?

the usual cause of this is just doing too much within the draw() loop. this runs (or tries to) 60 times a second, so even redrawing the entire chess board every time is probably going to result in high cpu. (maybe don't redraw the screen until something moves...)

but, like i say, without seeing the code we are just guessing.
