optiscaler/OptiScaler

OptiScaler bridges upscaling/frame gen across GPUs. Supports DLSS2+/XeSS/FSR2+ inputs, replaces native upscalers, enables FSR-FG/XeFG on non-FG titles. Supports Nukem mod for DLSSG-to-FSR3 FG.

About the project

OptiScaler is a middleware that intercepts upscaler calls in games (DLSS2+/FSR2+/XeSS) and redirects them to a chosen backend, allowing replacement of one technology with another. It also manages frame generation, including experimental OptiFG for DX12 and support for Nukem mod for DLSSG-to-FSR3 FG.

Useful for

Replace DLSS with FSR 3.1 in a game that only supports DLSS
Enable FSR-FG frame generation in a DX12 game without native support
Adjust RCAS sharpening and output scaling via OptiScaler overlay

Star trust

Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.

These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
