Anti-cheat, backups and download safety Learn the main OptiScaler safety concerns, including anti-cheat risk, third-party downloads, backups, DLL replacement, and reversible testing. ## 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 Learn the main OptiScaler safety concerns, including anti-cheat risk, third-party downloads, backups, DLL replacement, and reversible testing. ## Steps 1. Avoid online or anti-cheat protected games entirely. 2. Back up every file an install may replace. 3. Get builds from [Download](https://optiscaler.ink/download); do not assume a manager, client or mirror is part of the core project. 4. Remove the added files to return a game to stock. ## 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. ## Safety and anti-cheat: related searches - [Is OptiScaler Safe?](https://optiscaler.ink/keywords/is-optiscaler-safe) - [OptiScaler Safety](https://optiscaler.ink/keywords/optiscaler-safety) - [OptiScaler Safe](https://optiscaler.ink/keywords/optiscaler-safe) - [OptiScaler Anti-Cheat](https://optiscaler.ink/keywords/optiscaler-anti-cheat) - [OptiScaler Ban Risk](https://optiscaler.ink/keywords/optiscaler-ban-risk) - [Can OptiScaler Get You Banned?](https://optiscaler.ink/keywords/can-optiscaler-get-you-banned) - [OptiScaler Online Games](https://optiscaler.ink/keywords/optiscaler-online-games) - [Should I Use OptiScaler in Online Games?](https://optiscaler.ink/keywords/should-i-use-optiscaler-in-online-games) - [OptiScaler Account Risk](https://optiscaler.ink/keywords/optiscaler-account-risk) - [OptiScaler Offline Testing](https://optiscaler.ink/keywords/optiscaler-offline-testing) - [OptiScaler Test Offline](https://optiscaler.ink/keywords/optiscaler-test-offline) - [OptiScaler DLL Replacement](https://optiscaler.ink/keywords/optiscaler-dll-replacement) - [OptiScaler Backup DLL](https://optiscaler.ink/keywords/optiscaler-backup-dll) - [OptiScaler Download Safety](https://optiscaler.ink/keywords/optiscaler-download-safety) - [OptiScaler Download Safety 0.9.4](https://optiscaler.ink/keywords/optiscaler-download-safety-0-9-4) - [Is OptiScaler Safe 0.9.4?](https://optiscaler.ink/keywords/is-optiscaler-safe-0-9-4) - [Is OptiScaler Safe Linux?](https://optiscaler.ink/keywords/is-optiscaler-safe-linux) - [How to Is OptiScaler Safe](https://optiscaler.ink/keywords/how-to-is-optiscaler-safe) - [OptiScaler Download Safety Linux](https://optiscaler.ink/keywords/optiscaler-download-safety-linux) - [OptiScaler How to Download Safety](https://optiscaler.ink/keywords/optiscaler-how-to-download-safety) - [Can OptiScaler Get You Banned 0.9.4?](https://optiscaler.ink/keywords/can-optiscaler-get-you-banned-0-9-4) - [Can OptiScaler Get You Banned Linux?](https://optiscaler.ink/keywords/can-optiscaler-get-you-banned-linux) - [OptiScaler Best Download Safety](https://optiscaler.ink/keywords/optiscaler-best-download-safety) - [OptiScaler Download Safety 2026](https://optiscaler.ink/keywords/optiscaler-download-safety-2026) - [OptiScaler Download Safety Reddit](https://optiscaler.ink/keywords/optiscaler-download-safety-reddit) - [OptiScaler Download Safety Tutorial](https://optiscaler.ink/keywords/optiscaler-download-safety-tutorial) - [OptiScaler Is Safe 0.9.4](https://optiscaler.ink/keywords/optiscaler-is-safe-0-9-4) - [OptiScaler Latest Download Safety](https://optiscaler.ink/keywords/optiscaler-latest-download-safety) - [OptiScaler Safe 0.9.4](https://optiscaler.ink/keywords/optiscaler-safe-0-9-4) - [OptiScaler Safety 0.9.4](https://optiscaler.ink/keywords/optiscaler-safety-0-9-4) - [How to Can OptiScaler Get You Banned](https://optiscaler.ink/keywords/how-to-can-optiscaler-get-you-banned) - [Is OptiScaler Safe 2026?](https://optiscaler.ink/keywords/is-optiscaler-safe-2026) ## 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/safety-anti-cheat-backups.md
