Treat manager/client tools as third-party until proven otherwise; the core install is a manual ZIP next to the game executable. 2. Verify any helper app's source before running it. 3. Prefer the documented manual install from [Download](https://optiscaler.ink/download). 4. Never enter account credentials into a manager-style tool. ## 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. ## Manager and Client: related searches - [OptiScaler Manager](https://optiscaler.ink/keywords/optiscaler-manager) - [OptiScaler Client](https://optiscaler.ink/keywords/optiscaler-client) - [OptiScaler Manager and Client](https://optiscaler.ink/keywords/optiscaler-manager-and-client) - [OptiScaler Manager Download](https://optiscaler.ink/keywords/optiscaler-manager-download) - [OptiScaler Client Download](https://optiscaler.ink/keywords/optiscaler-client-download) - [Is OptiScaler Manager Official?](https://optiscaler.ink/keywords/is-optiscaler-manager-official) - [Is OptiScaler Client Official?](https://optiscaler.ink/keywords/is-optiscaler-client-official) - [OptiScaler Manager Safe](https://optiscaler.ink/keywords/optiscaler-manager-safe) - [Is OptiScaler Manager Safe?](https://optiscaler.ink/keywords/is-optiscaler-manager-safe) - [OptiScaler Third Party Manager](https://optiscaler.ink/keywords/optiscaler-third-party-manager) - [OptiScaler Third Party Client](https://optiscaler.ink/keywords/optiscaler-third-party-client) - [OptiScaler Helper Tool](https://optiscaler.ink/keywords/optiscaler-helper-tool) - [OptiScaler Manager vs Manual Install](https://optiscaler.ink/keywords/optiscaler-manager-vs-manual-install) - [OptiScaler Core Project](https://optiscaler.ink/keywords/optiscaler-core-project) - [OptiScaler Unofficial Manager](https://optiscaler.ink/keywords/optiscaler-unofficial-manager) - [Is OptiScaler Manager Safe 0.9.4?](https://optiscaler.ink/keywords/is-optiscaler-manager-safe-0-9-4) - [Is OptiScaler Manager Safe Linux?](https://optiscaler.ink/keywords/is-optiscaler-manager-safe-linux) - [How to Is OptiScaler Manager Safe](https://optiscaler.ink/keywords/how-to-is-optiscaler-manager-safe) - [OptiScaler Client Download 0.9.4](https://optiscaler.ink/keywords/optiscaler-client-download-0-9-4) - [OptiScaler Manager Download 0.9.4](https://optiscaler.ink/keywords/optiscaler-manager-download-0-9-4) - [OptiScaler Manager vs Manual Install 0.9.4](https://optiscaler.ink/keywords/optiscaler-manager-vs-manual-install-0-9-4) - [Is OptiScaler Client Official 0.9.4?](https://optiscaler.ink/keywords/is-optiscaler-client-official-0-9-4) - [Is OptiScaler Manager Official 0.9.4?](https://optiscaler.ink/keywords/is-optiscaler-manager-official-0-9-4) - [Is OptiScaler Client Official Linux?](https://optiscaler.ink/keywords/is-optiscaler-client-official-linux) - [Is OptiScaler Manager Official Linux?](https://optiscaler.ink/keywords/is-optiscaler-manager-official-linux) - [OptiScaler Manager and Client 0.9.4](https://optiscaler.ink/keywords/optiscaler-manager-and-client-0-9-4) - [OptiScaler Manager Safe 0.9.4](https://optiscaler.ink/keywords/optiscaler-manager-safe-0-9-4) - [How to Is OptiScaler Client Official](https://optiscaler.ink/keywords/how-to-is-optiscaler-client-official) - [How to Is OptiScaler Manager Official](https://optiscaler.ink/keywords/how-to-is-optiscaler-manager-official) - [Is OptiScaler Manager Safe 2026?](https://optiscaler.ink/keywords/is-optiscaler-manager-safe-2026) - [Is OptiScaler Manager Safe Reddit?](https://optiscaler.ink/keywords/is-optiscaler-manager-safe-reddit) - [Is OptiScaler Manager Safe Tutorial?](https://optiscaler.ink/keywords/is-optiscaler-manager-safe-tutorial) ## 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. ## Related - [OptiScaler guides: install, FSR4, Linux, performance and safety](https://optiscaler.ink/guides) - [OptiScaler FAQ: the official 20 questions, answered](https://optiscaler.ink/faq) - [OptiScaler install guide: clean setup from start to finish](https://optiscaler.ink/guides/install-optiscaler-clean-setup) - [How OptiScaler works: input, output and overlay explained](https://optiscaler.ink/guides/how-optiscaler-works-input-output) - [OptiScaler compatibility guide for DirectX 11, DirectX 12 and Vulkan](https://optiscaler.ink/guides/compatibility-dx11-dx12-vulkan) ## Download ZIP next to the game executable: [Download OptiScaler](https://optiscaler.ink/download) Markdown mirror: https://optiscaler.ink/guides/manager-and-client-safety.md
