News AMD and Valve Working on CPU Driver That Could Boost Steam Deck Performance

Given that this system runs a Linux-based OS, Valve has to optimize the software as much as possible to ensure a smooth and consistent gaming experience across various AAA titles

Linux already runs really fast compared to Windows. Still, software should be as optimized as much as possible when targeting specific hardware.

AMD will share more details about its work on the scaling driver at the X.org Developer Conference (XDC)
This is interesting because Steam Deck will be running under Wayland with a custom compositor. Since Wayland is the successor to X.Org and they are showing this off at the X.Org Developer Conference, it could be pointing to them sharing the code behind this.
