Handheld Companion – Release Notes

0.28.1.4 - Wake & Play

With this release, a lot of efforts went into reducing our CPU footprint and ensuring faster resume when system wakes up. We’ve also begun replacing WinRing0 with PawnIO (safer; fewer AV false positives) although this is only partial implementation for now, as power manipulation still uses WinRing0. On popular request, settings will now live in %LocalApplicationData%. During first launch, a backup is automatically written in %MyDocuments%.

Device Support

• Lenovo Legion Go 2 — full device support (known issue: left controller gyro Z axis is reverted, we encourage you in using right controller for gyro, under the device page settings).
• AYANEO Flip DS 1S — full device support (including bottom screen brightness control).
• MSI Claw - 10F BIOS partial support (we strongly discourage anyone to deploy this BIOS as it causes issues with the top right OEM button).
• Added AMD CPU support for Strix Point, Dragon Range, Fire Range, HX370 (Pro), Krackan Point.

System Usage Reduction

• Reduced CPU usage in DInputController.
• Lower CPU cost in HidLibrary I/O.
• Reduced ThreadPool pressure in RaiseInputsUpdatedAsync.
• Lowered CPU usage in RadioMonitor.
• Lighter CPU path via LibreHardwareMonitor class adjustments.
• SDL controllers now use Tick() instead of input pumping (helps CPU).
• Updated WPF PresentationCore for stability/perf.

New & Updated

• Layout Mapping: Trigger to Button options.
• SDL: updated to SDL3 3.2.24.
• fr-FR translation refresh by @moi952.

Navigation & UI

• Gamepad UI navigation now supports HyperlinkButton.
• Bottom bar buttons: click behavior fixed and consistent.
• ProfilesPage shows saved Windows settings next to live values.
• Improved screen friendly-name detection.

Stability & Resume

• Reduced resume delays from sleep/hibernation.
• More stable virtual controller on resume.
• New setting: Unhide controller on disconnect.
• Improved controller unhide when app closes.

Fixes

• Rendering — UI could fail after toggling GPU acceleration.
• Rendering (resume) — UI not drawing after sleep/hibernation.
• Controllers — Infinite rumble after power-cycle while rumbling.
• Controllers (SDL) — Trigger mapping to LB/LBSoft/RB/RBFull (DualShock/DualSense/…).
• Preferred device — Better selection when plugging/unplugging.
• Hotkeys — Default hotkeys deploy if none found; keyboard-triggered hotkeys with SDL.
• MSI Claw (DInput) — Crash while controller was cycling.
• AsusACPI — Resume stability.
• CPU telemetry — Power/temperature readings corrected (requires PawnIO).
• Favorites — Sub-profile management reliability.
• Main Window — Visibility in Task View when minimized.
• About page — Device illustration.
• IGDB — Artwork download flow.
• QuickTools (AYANEO Flip) — Touch keyboard height.
• Misc crashes and exceptions hardened.
