Use turbomode and turbowarp: https://turbowarp.org/560218149?turbo I've gotten around 800 fps on scratch, 87k on turbowarp If you're wondering about that weird plane overlay, it's because I haven't added a 'backface culling' sort of function yet, which I promise I will in version 3. Oh and new additions: -You can see the x, y, and z the ray lands on the cube, seen by the pen color on the render. -I made the movement the same for every fps, hope that helps -I added 8 cubes -The origin is now based around the camera, not translating cubes which were annoying
