Per-Core EPP Boost in AMD P-State Could Lift Steam Deck FPS
A patch series to the AMD P-State Linux driver adds an opt-in per-core Energy Performance Preference (EPP) boost that selectively raises busy cores to a performance state for short bursts. In tests on the Steam Deck running Civilization VI, 1%-low FPS improved by about 31.8% and p99 frame times also improved, though the patches require review before mainline and require enabling the epp_boost parameter to activate. This could boost Linux gaming on handhelds, but broader testing and kernel acceptance are still pending.
