That moment when you realize that you need more power for your idea. First number is the FPS (precise with millisec). Looks like it's soon going to be time to get back into C/C++.

I knew it wouldn't run perfectly, but man; can't even get 60 fps with 32x32 pixel wide rays

Maybe you can make some optimization of your code?

It probably does need optimization. The only problem is that it's so precise, I can't just lazily ray cast, and I can't think of any real good ways to optimize.

I can try to help with it

If your map is big then try to limit the distance the rays go.
