Since I am seeing posts from time to time with claims that the Steam Deck is already at its performance limit, I wanted to show that future software updates & tweaks can still have a pretty profound positive impact on gaming results.
For that I am using the CachyOS Handheld Edition with the latest Linux 6.16 kernel on my LCD Deck without any hardware overclock, but changing quite a few software settings like using BPFland as the CPU scheduler and disabling all CPU mitigations.
Except for the mitigations thing, most of these software improvements should eventually end up within SteamOS, too.
As an example of the performance uplift, here is my result of the free Black Myth Wukong benchmark tool (without any framegen!):
So yeah, the future potential for gaming on the Steam Deck is looking very bright indeed!
