There's still room for improvement, but Linux gaming has come a long way in a short time.

I remember when Proton launched it was like magic playing games like Doom and Nier Automata straight from the Linux Steam client with excellent performance. I do not miss the days of having the Windows version of Steam installed separately.
Windows too busy using those cpu cycles to gather your usage metrics for sale to third parties.
Somewhat true, but the truth is that the CPU scheduler on Windows is just awful. It literally wastes performance because it doesn't optimize instructions as efficiently as schedulers on other OSes.
Without going into details, we ported an application that I worked with that did complex scientific calculations to Linux. All the calculations code was done in C and C++ so it was 99.9% OS agnostic. We consistently got at least a 50% performance increase when running on Linux as opposed to Windows. We tested just about every edition of Windows from Windows 8/Server 2013 to Windows 10/Server 2019. The version of Windows that did best was Windows 7 and Linux was 50% faster. All the other editions were slower.
And the distro of Linux didn't matter much. A few percent difference here and there, but all of them were astonishingly faster than Windows.
