# 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.

## What it is
OptiScaler is a Windows tool that lets gamers replace upscalers in games that already support DLSS2+/FSR2+/XeSS and manage frame generation, including enabling FSR-FG/XeFG on titles without native support. It bridges upscaling and frame generation technologies across NVIDIA, AMD, and Intel GPUs with extensive customization options.

## Use cases
- replace DLSS with FSR in a game on an AMD GPU
- enable frame generation in a DX12 game that lacks native FG support
- use XeSS instead of DLSS on an Intel Arc card
- force FSR3 frame generation on a non-FG title
- customize upscaler settings per game
- use DLSSG-to-FSR3 frame generation via Nukem mod

## When to choose
- you want to swap upscalers in a game that already supports DLSS2+/FSR2+/XeSS
- you have an AMD or Intel GPU and want DLSS-quality upscaling alternatives
- you want frame generation in DX12 games without native FG support
- you need fine-grained control over upscaler and FG behavior per game

## When to avoid
- your game has no DLSS2+/FSR2+/XeSS support to hook into
- you need a solution for Linux or console gaming
- you want a simple one-click enhancer without per-game configuration
- your game uses DX11 or Vulkan only for frame generation features
