Decky HelixSR Manager has been released in version 0.11.0.

The Decky plugin installs HelixSR, a DLSS-network-based replacement for FSR 3.1 that runs on AMD GPUs like the one in the Steam Deck, on a per-game basis, including download, build and deployment.

The new version supports HelixSR 3.1.0 and installs its HLX FSR 4 either through the game’s OptiScaler or in place of FSR 3.1. The HelixSR 2.0.0 (DLSS) network can be used alongside it. The build now additionally downloads about 420 MB of AMD’s driver package.

Release 0.11.0: HelixSR 3.1.0

HelixSR 3.x support

• HLX FSR 4: from 3.0, HelixSR’s releases put HLX FSR 4 (AMD’s FSR 4 network on HelixSR’s pipeline) into games. The plugin builds and installs it, either through the game’s OptiScaler or in place of the game’s own FSR 3.1. AMD’s own FSR stays next to it, for comparing and for anything HLX FSR 4 doesn’t cover.
• Build: building a 3.x release adds a second step that downloads about 420 MB of AMD’s driver package. It only reads the FSR 4 file, installs nothing, and adds several minutes. HelixSR’s own game installer still never starts.
• HelixSR 2.0.0’s DLSS network next to 3.x: with 2.0.0 downloaded and built, a 3.x release’s OptiScaler section offers both Install HLX FSR 4 and Install HelixSR 2.0.0 (DLSS network). Each install can swap to the other with Use … instead.
• HLX DLSS isn’t offered. HelixSR 3.x’s own DLSS network is made for HelixSR Scaler. In a game’s own OptiScaler (0.10), OptiScaler decides the Deck’s GPU can’t do DLSS and quietly uses FSR 2.1.2 instead. HelixSR 2.0.0 is the DLSS network option for now.
• Status check: knows HLX FSR 4. The panel says when it worked, when AMD’s FSR stepped in, or when it can’t upscale.

Fixes

• “The log is older than the last game session” no longer appears wrongly after sessions longer than a minute.
• The DLSS launch option (HelixSR 1.5) now also sets DXVK_NVAPI_ALLOW_OTHER_DRIVERS=1. An option added by an older version is offered again.

Tested

Steam Deck OLED, The Witcher 3 through its OptiScaler: HLX FSR 4 (3.1.0) and HelixSR 2.0.0 next to it.

Updating

Press Update in the panel, or install the zip over the old one. In each game, Switch to HelixSR … replaces the old install; no cleanup needed.
