Linux kernel patch can boost the Steam Deck’s 1% low frame rate by as much as 31% in early testing
Linux kernel patches are delivering notable performance improvements to the Steam Deck, Valve’s handheld gaming device running on SteamOS. According to early testing, a new ’epp_boost’ feature for the AMD P-State driver can boost 1% low frame rates by as much as 31%, potentially providing significant smoothness improvements during performance-demanding gameplay.
The feature was developed by David Vernet, a Linux kernel engineer at Meta, and implements per-core Energy Performance Preference (EPP) for AMD CPUs. This granular approach to power management allows individual CPU cores to optimize their energy and performance settings independently, which can lead to better frame time consistency in gaming scenarios where the 1% low frame rate metric is particularly important for perceived smoothness.
The patches remain under review and haven’t yet been formally accepted by AMD’s Linux kernel engineers, suggesting they’re still in early stages. If merged into the mainline kernel, these optimizations could benefit not only Steam Deck users but potentially other devices running AMD processors with Linux-based operating systems. The development represents ongoing efforts to squeeze more performance from existing hardware through software optimization rather than requiring physical upgrades.
