HelixSR 1.9.3 corrects the frame-generation restriction in 1.9.2: alternative frame generation is available again. Only HelixSR's experimental frame generation is withdrawn.
- Keeps FSR, XeSS and other supported Scaler frame-generation providers selectable, with their usual game/GPU requirements and runtime dependencies.
- Preserves alternative FG input, output, enabled state and provider settings when updating. An older HelixSR provider choice is redirected to FFX; HelixSR is excluded from provider fallback and cannot be selected in the menu.
- Retains the 1.9.0 INT8 calibration and layer selection, Speed Boost Auto / On / Off, reactive-mask support and newer upscaling fixes from 1.9.2.
- Includes HelixSR Scaler 1.0.6. HelixSR's own FG engine and setup downloads remain absent.
Already installed 1.9.2? Update, then select your preferred alternative again in Scaler's Frame Generation menu. Version 1.9.2 disabled those settings. Enable a reactive mask by unticking Disable Reactive Mask in Scaler and restarting; the game must supply a mask.
Extract HelixSR-1.9.3.zip and run helixsr-setup.bat (Windows) or helixsr-setup.sh (Linux / Steam Deck). Standalone Scaler packages and HelixSR Desktop 1.0.3 installers are also included.
Validation checks startup routing and preservation of alternative settings, installer upgrades/removal, and upscaling API behavior. It does not establish image quality or performance for every FG provider or GPU.
