# Does OptiScaler improve performance? Honest expectations

No. Results vary by game, GPU, resolution, output mode, frame generation, and whether translation overhead is involved. Measure frame time in the scene you actually play.

## Facts (2026-10-18)

- **Version:** OptiScaler 0.9.4 (reference build, July 2026)
- **APIs:** DirectX 11, DirectX 12, Vulkan
- **Upscalers:** DLSS, FSR and XeSS inputs/outputs where compatible
- **Frame generation:** Experimental OptiFG (DirectX 12)
- **Overlay:** Insert key
- **Install:** ZIP extracted next to the main game executable
- **Platform:** Windows; Linux via Proton/Wine varies
- **Site:** Independent guide — not the official project site

## In short

No. Results vary by game, GPU, resolution, output mode, frame generation, and whether translation overhead is involved. Measure frame time in the scene you actually play.

## Steps

1. Benchmark the stock game first.

2. Install and test the same scene.

3. Compare frame time and stability, not one peak FPS number.

4. Keep the setup only if it wins honestly.

## 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.

## FAQ

### 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.
