Install OptiScaler the reversible way: download the ZIP, back up, extract next to the main game executable, launch offline, press Insert.

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.
