Windows Was The Problem All Along - Dave2D
We could obviously compare performance between windows and steamOS before on the steam deck, or between windows and Bazzite on other handhelds. But this is the first time we have had official windows and SteamOS builds for the same hardware.
Does this look optimized to you, Windows side?
While I get it, it does look pretty damning, skepticism when we haven’t been presented with rigorous documented testing is always good. I don’t think ex: gamersnexus is going to find different results, but I’m pretty damn sure they’ll at least be comparing chipsets to ensure the hardware actually is identical (and making sure that things like system settings are configured to be as fair as possible). Lets not be apple fans and leap to the top of the superiority heap just because a good looking infographic said we should.
No, because Windows isn’t optimized for games. It is for general use, including games.
