# OptiScaler on Windows, Linux Proton, DX11, DX12 and Vulkan

Where OptiScaler runs and what changes per platform and API: Windows first, Linux through Proton/Wine.

## 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

## What this hub is

Where OptiScaler runs and what changes per platform and API: Windows first, Linux through Proton/Wine.

OptiScaler 0.9.4 is a community translation layer for DirectX 11, DirectX 12 and Vulkan games. This host is an independent guide, not the official project site. Start from [Download](https://optiscaler.ink/download), then come back here for the per-game checks.

## The safe order

1. Back up the game folder.

2. Extract the ZIP next to the main game executable.

3. Launch offline and press Insert.

4. Change one output at a time, and never test in online or anti-cheat protected games.

## Pages in OptiScaler on Windows, Linux Proton, DX11, DX12 and Vulkan

- [OptiScaler on Windows](https://optiscaler.ink/platforms/windows) — Windows is the primary desktop environment: extract the ZIP next to the game executable, launch, and press Insert.

- [OptiScaler on Linux through Proton](https://optiscaler.ink/platforms/linux-proton) — Linux use is possible in supported configurations, commonly through Proton or Wine, but Vulkan, driver, and upscaler requirements can differ from Windows.

- [OptiScaler on DirectX 11 games](https://optiscaler.ink/platforms/directx-11) — DirectX 11 is supported, although the available output methods and behavior can differ from DirectX 12.

- [OptiScaler on DirectX 12 games](https://optiscaler.ink/platforms/directx-12) — DirectX 12 has broad support and is also the API used by experimental OptiFG functionality.

- [OptiScaler on Vulkan games](https://optiscaler.ink/platforms/vulkan) — Vulkan support exists, but individual upscalers and games can require specific compatibility conditions.

- [OptiScaler on AMD Radeon GPUs](https://optiscaler.ink/platforms/amd-gpus) — FSR outputs are the usual target on Radeon. FSR4 depends on GPU capability, driver or SDK behavior and game compatibility, with fallback possible.

- [OptiScaler on NVIDIA GeForce GPUs](https://optiscaler.ink/platforms/nvidia-gpus) — Common route: a DLSS input redirected to an FSR or XeSS output for testing, or kept on DLSS with overlay tuning.

- [OptiScaler on Intel Arc and integrated GPUs](https://optiscaler.ink/platforms/intel-gpus) — XeSS output is the natural target on Intel hardware; availability still depends on the game's input and API path.

## 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.
