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
