Download OptiScaler 0.9.4

In short

Common causes include an incorrect install folder, the wrong proxy DLL, input-hook conflicts, overlays, or a game-specific compatibility issue.

Steps

  1. Confirm the files sit next to the main game executable, not a launcher stub.
  2. Confirm the proxy DLL name matches the setup for that game and API.
  3. Close other overlays and input hooks, then retry Insert.
  4. Remove the files, verify the game runs stock, and re-install the minimum setup.

Facts that do not change

Reference build is OptiScaler 0.9.4. Install is a ZIP next to the main game executable; the overlay opens with Insert. Avoid online or anti-cheat protected games, and test offline first.

Frequently asked questions

What is OptiScaler?

OptiScaler is a community tool that can intercept supported in-game upscaler calls and redirect them to another supported upscaling backend, with additional tuning options.

How does OptiScaler work in a game?

The game exposes an input upscaler, OptiScaler sits between the game and the selected output backend, and the chosen output handles the final upscaling path where compatibility allows.

Does OptiScaler support DirectX 11?

Yes, DirectX 11 is supported, although the available output methods and behavior can differ from DirectX 12.

Does OptiScaler support DirectX 12?

Yes. DirectX 12 has broad support and is also the API used by experimental OptiFG functionality.

Practical Checklist

  • Keep original files backed up before changing the game folder.
  • Test one setting or backend at a time.
  • Avoid anti-cheat protected online sessions.
  • Document the working configuration before updating.
