I saw a claim that Windows 7 is superior to Windows 10 for gaming:
There’s a lot of reasons win7 is utilized. Especially in strictly competitive games that support it, (CSGO, Valorant, Fortnite), a lot of the time it’s a superior option due to lower latency and sometimes even better 0.1/1% lows depending on configuration, which are much more important than average FPS in those games. (Anyone can test this through CapFrameX and MLC.)

I cannot find much evidence in support of this though. These results seem to have been refuted: http://www.lofibucket.com/articles/dwm_latency.html
And this video shows Windows 10 running faster than Windows 7, at least in some games: https://www.youtube.com/watch?v=G8rotnrhTuc
But maybe there are intricacies I am missing. So, is Windows 7 better than Windows 10 for gaming?
