Fascinating. Just for fun, comparable compute (by cpumarks) to your 13900k for 30 fps would be 39,600+ 96-core AMD EPYC 9655Ps. Bravo on the project success!
Reminds me of the guy on Youtube obsessed with optimizing Mario64 code, he found really interesting things like how removing optimizations made the game faster - presumably because the very basic tooling the original developers had made it hard to measure things across the board, and also not making the most of the powerful hardware architecture.
