I benchmarked my gaming PC on Windows vs Linux, and the difference was bigger than I expected

I’ve got a dual-booting PC with both Windows 11 and EndeavourOS Linux on it, which puts me in the best position to compare benchmarks across operating systems. It’s the same machine, after all, with the same CPU, GPU, RAM, SSD, etc. The hardware variables disappear when benchmarking on Windows and Linux, and it’s as controlled a test as I can get.
