Steps

  1. Fix resolution and quality preset before touching advanced values.
  2. Change one setting at a time and re-test the same scene.
  3. Watch frame time and image stability, not only average FPS.
  4. Keep a copy of the working INI before experimenting.

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.
