Both versions were tested on Steam Deck OLED models with no CryoUtilities and a UMA Buffer set to 1G (default).

No, just no, I hate testing like this, it’s not a stock deck with the 1G uma buffer, it’s just not, and the OLED deck is already known to be more power efficient and has a small fps improvement due to that power efficiency. They should be testing with the middle ground LCD deck with no buffer modifications and then test with modifications to see the difference.
