Does SteamOS 3.8.1 improve performance on the GPD Win 5?

SteamOS 3.8.1 Preview improves performance by reducing controller input latency to under 500 microseconds and optimising VRR frame pacing for smoother visuals. Community benchmarks also suggest a roughly 10% increase in FPS for titles using FSR4 compared to stable builds.

Can I control the TDP of my third-party handheld natively?

Native TDP control is now supported for the ASUS ROG Xbox Ally series within the Quick Access Menu of SteamOS 3.8.1. For GPD and OneXPlayer devices, improved controller support is present, though full native TDP integration is still in the "preliminary support" phase for some models.

Will this update fix the SD card issues on the ROG Ally?

Valve has included specific SD card reliability improvements for the ASUS ROG Xbox Ally, Legion Go, and MSI Claw in this update. These fixes address the thermal and driver-level instabilities that previously caused data corruption on those devices.

Is the input latency reduction noticeable in games?

The reduction from 8ms to 100-500us is highly noticeable in competitive titles and fast-paced platformers. This 10x improvement brings handheld controller responsiveness in line with high-end wired desktop peripherals.
