# OptiScaler Manager and Client: what is actually official?

Do not assume a third-party manager or client is part of the core OptiScaler project. The documented install is a manual ZIP next to the game executable.

## 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

Do not assume a third-party manager or client is part of the core OptiScaler project. The documented install is a manual ZIP next to the game executable.

## Steps

1. Check who publishes the manager/client and where it is hosted.

2. Compare it against the manual ZIP install.

3. Never enter game-account credentials into it.

4. When in doubt, install manually.

## 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.
