of course its not all games, but it becomes significantly more messy for the reviewer to test it becuase you start getting anomolous data based on a decision made in advance.
also its a phoronix review, and last I recall, raytracing is spotty on linux and dependant if it uses wine or not. in the case for liek cyberpunk it does, but if a game doesnt natively have raytracing, its uses are more mixed
which phoronix in question doesn't do a raytracing section in particular with, so what data are yuou expecting phoronix to pump out? Their literal choice for raytracing is Quake RTX, as its linux native title. This is a situation where you're looking at the wrong type of reviewer if you want a specific piece of content.
