just showcase… Im not sure why is it so laggy (anyways it does 600 operations per frame)
i also tried to make mirrors

Not bad but I would suggest adding more of a depth perception to it as it looks a bit bland. It’s also probably laggy because you haven’t use parallel luaU. Try that.

I’m not even sure what you can do with parallel lua. The only things you can do are calculations, anything vanilla - and this uses raycasting which isn’t so there’s not much use for parallel lua.
This is my raycaster engine I made last year. Runs well over 100 fps at 240x240 with textures and floor/ceiling rendering. No parallel luau or multithreading. The only real optimization i made was using a custom raycasting algorithm specifically for tile maps to reduce the amount checks done during the raycast via the DDA algorithm
I suspect the lag might be coming from your for loops, im not sure why else it would be lagging that bad.
Be sure you’re only doing a for loop for each column for the main raycasting and distance maths and calculations. Not every pixel.

No, you definitely can do that with parallel luaU.
