Weird, no one has reported this problem before.

To be fair, my computer is rather old and isn't eligible for windows 11, however it can run Roblox with very few problems, so I'd expect it to be able to run this game. I noticed that there are shaders in the files, so maybe add a way to turn off the ones that aren't needed? It just seems like it didn't take into account lower end devices and thus isn't properly optimized to run on them.
