Interesting, this crashed my browser tab trying to load it! Run for all of 15s at about 1fps ;) I'm of course, not on a phone, but on my 9800X3D desktop, which promptly spiked usage to 100%! I wonder what APIs are not available on a desktop that this uses.
I kept getting "Driver Message (OpenGL, Performance, GL_CLOSE_PATH_NV, High): GPU stall due to ReadPixels", which for anyone familiar with OpenGL probably knows... usage of the glReadPixels function is typically frowned upon if at all possible, because moving framebuffer data out of the GPU and back into system memory can cause huge performance issues.
I'm not sure why they need to use this function, or if it's just not optimized enough to go without it.
