I have no doubt that "bare metal" games' performance is better under Linux but what about things like cpu scheduling for multicore or directstorage?
I've never heard about directstorage before, and by the description it's an xbox api, does windows even support it?
That's not really impressive, you get 100k iops without any tweaking at all and cpu shouldn't even blink at it.
And linux has io_uring which can handle millions of syscalls from a single thread without breaking a sweat. In my experience, I/O on Windows is just really slow, every file operation takes 10s to 100s of times longer than on any Unix-like kernel (1000s if windows defender is enabled)
