It doesn't make sense to benchmark a handheld gaming device w/ a native screen resolution of 1920x1200 at 2k or 4k. Likewise setting any graphics settings "extreme" like raytracing - it will run at slideshow speeds no matter what operating system. Besides, DOOM: The Dark Ages is a top tier graphics title released a month and a half ago; I think the selection of titles is decent for capability of the device.
From my personal experience overall games run much much better on Windows ( 10 or 11 ).
Edit: ok I just noticed the title is missleading, it's for handled device not pc.
