OptiScaler Client 1.0.6 adds Heroic Games Launcher support, experimental gamepad support, FSR 4.1.1 for older GPUs

Added

• Platform & Launcher Integrations

  • Heroic Games Launcher Support: Compatibility and integration for Heroic Games Launcher have been added (by @misterj05).
  • AUR Support: Added Arch User Repository (AUR) support for Linux users.
  • Nix Support: A Nix devShell and build derivation have been implemented (by @jorikvanveen).

• Controller Support

  • Gamepad Support (Beta): Added experimental gamepad navigation support for both Windows and Linux. Controls can be found in the Help view. (Note: This is currently in beta, so some interactions may not feel completely fluid. Feedback and bug reports are welcome!)

• Game Management & Filtering

  • Advanced Filtering & Favorites: Three new filters have been added to the Games view, and games can now be marked as favorites.
  • Real-time Filtering: Game filtering can now be performed in real-time without needing to scan from scratch.
  • OptiScaler Compatibility Integration: A new section has been added to the Manage view for each game, displaying its recommended configuration fetched directly from the OptiScaler compatibility page.
  • Help Resources: The Help view now includes a direct link to the OptiScaler compatibility list.

• Upscaler Capabilities

  • FSR 4.1.1 (Non-RDNA4): Experimental support for FSR 4.1.1 on non-RDNA4 graphics cards has been included. (Note: This has not been extensively tested; bug reports are appreciated).

Improvements

• Steam Integration Enhancements

  • Steam File Parsing Refactor: The parsing logic for Steam files has been refactored to use the robust ValveKeyValue library (by @brittcraft).

• Version Management

  • Smart Version Sorting: Lists for OptiScaler, OptiPatcher, and FSR INT8 now automatically sort to show the latest available version first. This behavior can be toggled via a new switch in the settings (enabled by default).

• Visual & UI Refinements

  • Native vs. Added Upscalers Differentiation: Native in-game upscalers and those included via OptiScaler are now visually differentiated. Added upscalers will appear without a background on game covers and will display a purple border in the Manage view.

• Linux Specifics

  • Default Configuration Path: The default configuration path for Linux users has been moved to ~/.config or ~/.local for properly saving settings and client assets.

• Localization

  • Simplified Chinese Translation: Corrected and updated the Simplified Chinese translation (by @juij-fun).

Fixes

• Installation & Updates

  • Settings Backup & Restore: Fixed an issue where game-specific settings were lost when updating OptiScaler. Settings are now backed up and restored automatically during updates.
  • Reinstallation Functionality: Resolved a bug where reinstalling OptiScaler via the client caused it to lose functionality.

• Linux & SteamOS Fixes

  • FSR4 INT8 Deployment Bug: Fixed a bug on SteamOS where the client failed to copy the FSR4 INT8 bundle to the correct game folder, preventing the OptiScaler GUI and FSR4 options from loading (e.g., in Achilles: Legends Untold).
