Frame Generation Options

FG Source and FG Output

With the release of OptiScaler 0.9, the FG section has received a major rewrite/revamp in order to expand support for different tech. This section will try explaining each setting and recommended use cases.

FG Source - the native FG which the game supports

• FG settings received a major rewrite/revamp
  • Added enable/disable FG shortcut key - default is End (customisable, Keybinds in Overlay, FGShortcutKey in INI)
  • Some options aren't supported and may be implemented down the line (e.g. XeFG as FG Source, DLSSG as FG Output)
  • HUDless logic improved
  • OptiScaler now comes bundled with latest Fakenvapi (1.3.9.1) and Nukems dlssg-to-fsr3 (0.130)
  • FG Sources (game FG inputs AKA what you select in the game) and FG Outputs (what you want to convert to with Opti) - you need to select both now
    • DLSSG via SL FG Source is recommended, then FSR-FG then OptiFG/Upscaler as a final resort
    • DLSSG via Streamline inputs (only DX12 and Streamline 2+ games, doesn't support a small number of old SL1 games, tooltip warns about unsupported version)
      • Required to enable DLSS-FG in the game and then tick (FG) Active in Opti's overlay
      • This is our own equivalent of Nukem's mod which is a lot more versatile, albeit a bit less (legacy) compatible as noted
    • Nukem's DLSSG is locked to FSR3.1 FG as that's the only option (Nukem's DLSSG -> FSR3-FG via Nukem's)
      • Also requires DLSS FG activated in-game
    • OptiFG (Upscaler) now also supports XeFG, in addition to FSR3/4-FG
      • OptiFG is without the HUDless resource, but unlike FSR3 FG, XeFG/FSR4-FG does interpolate the HUD variably well (might not even require HUDfix), while FSR3-FG requires HUDfix always
    • FSR 3.1/FSR3.0 FG Sources
      • Also a new addition for games that have native FSR3.1/FSR3.0 FG, can be a bit finnicky
      • Requires FSR-FG enabled in game settings
