OptiScaler: Bridges upscaling/frame gen across GPUs (12k stars)
What it does
All text below is quoted directly from the project README.
>OptiScaler bridges upscaling/frame gen across GPUs. Supports DLSS2+/XeSS/FSR2+ inputs, replaces native upscalers, enables FSR-FG/XeFG on non-FG titles.
Key aspects of OptiScaler:
- Enables usage of XeSS, FSR2, FSR3, FSR4 (officially, RDNA4 and RDNA3 dGPUs only) and DLSS in (temporal) upscaler-enabled games
- Allows users to fine-tune their upscaling experience with a wide range of tweaks and enhancements (RCAS & MAS, Output Scaling, DLSS Presets, Ratio & DRS Overrides etc.)
- Since v0.7.0+, added experimental DX12 frame generation support with possible HUDfix solution (OptiFG)
- Supports Fakenvapi integration - enables Reflex hooking and injecting Anti-Lag 2 (RDNA1+ only), LatencyFlex (LFX) or XeLL - bundled since 0.9
- Since v0.7.8, added ASI plugin loading support (disabled by default (LoadAsiPlugins= in INI), loads from customisable folder, default plugins)
- Since v0.7.8, OptiScaler is now automatically applying certain game patches for a better out-of-the-box experience
- Since v0.9.0, separated FG Inputs and Outputs, added XeFG and FSR4-FG support, as well as bundled Fakenvapi and Nukem's FSR3-FG mod
>OptiScaler is FREE, any kind of monetary requirements are scams!
