Fix resolution and quality preset before touching advanced values. 2. Change one setting at a time and re-test the same scene. 3. Watch frame time and image stability, not only average FPS. 4. Keep a copy of the working INI before experimenting. ## 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. ## Performance and settings: related searches - [OptiScaler Performance Settings](https://optiscaler.ink/keywords/optiscaler-performance-settings) - [Best OptiScaler Performance Settings](https://optiscaler.ink/keywords/best-optiscaler-performance-settings) - [OptiScaler Best Settings](https://optiscaler.ink/keywords/optiscaler-best-settings) - [OptiScaler Settings Guide](https://optiscaler.ink/keywords/optiscaler-settings-guide) - [OptiScaler Performance Tuning](https://optiscaler.ink/keywords/optiscaler-performance-tuning) - [OptiScaler Performance Baseline](https://optiscaler.ink/keywords/optiscaler-performance-baseline) - [OptiScaler Output Backend](https://optiscaler.ink/keywords/optiscaler-output-backend) - [OptiScaler Quality Ratio](https://optiscaler.ink/keywords/optiscaler-quality-ratio) - [OptiScaler Output Scaling](https://optiscaler.ink/keywords/optiscaler-output-scaling) - [OptiScaler Sharpening](https://optiscaler.ink/keywords/optiscaler-sharpening) - [OptiScaler Sharpening Settings](https://optiscaler.ink/keywords/optiscaler-sharpening-settings) - [OptiScaler Frame Generation Settings](https://optiscaler.ink/keywords/optiscaler-frame-generation-settings) - [OptiScaler Stutter](https://optiscaler.ink/keywords/optiscaler-stutter) - [OptiScaler Stutter Fix](https://optiscaler.ink/keywords/optiscaler-stutter-fix) - [OptiScaler Performance Loss](https://optiscaler.ink/keywords/optiscaler-performance-loss) - [OptiScaler Translation Overhead](https://optiscaler.ink/keywords/optiscaler-translation-overhead) - [Does OptiScaler Improve Performance?](https://optiscaler.ink/keywords/does-optiscaler-improve-performance) - [Does OptiScaler Improve FPS?](https://optiscaler.ink/keywords/does-optiscaler-improve-fps) - [OptiScaler Image Quality](https://optiscaler.ink/keywords/optiscaler-image-quality) - [OptiScaler Graphics Quality](https://optiscaler.ink/keywords/optiscaler-graphics-quality) - [OptiScaler Optimization](https://optiscaler.ink/keywords/optiscaler-optimization) - [OptiScaler Performance Tool](https://optiscaler.ink/keywords/optiscaler-performance-tool) - [Does OptiScaler Improve FPS 0.9.4?](https://optiscaler.ink/keywords/does-optiscaler-improve-fps-0-9-4) - [Does OptiScaler Improve Performance 0.9.4?](https://optiscaler.ink/keywords/does-optiscaler-improve-performance-0-9-4) - [Does OptiScaler Improve FPS Linux?](https://optiscaler.ink/keywords/does-optiscaler-improve-fps-linux) - [Does OptiScaler Improve Performance Linux?](https://optiscaler.ink/keywords/does-optiscaler-improve-performance-linux) - [How to Best OptiScaler Performance Settings](https://optiscaler.ink/keywords/how-to-best-optiscaler-performance-settings) - [How to Does OptiScaler Improve FPS](https://optiscaler.ink/keywords/how-to-does-optiscaler-improve-fps) - [How to Does OptiScaler Improve Performance](https://optiscaler.ink/keywords/how-to-does-optiscaler-improve-performance) - [Best OptiScaler Performance Settings 0.9.4](https://optiscaler.ink/keywords/best-optiscaler-performance-settings-0-9-4) - [OptiScaler Best Settings 0.9.4](https://optiscaler.ink/keywords/optiscaler-best-settings-0-9-4) - [Best OptiScaler Performance Settings Linux](https://optiscaler.ink/keywords/best-optiscaler-performance-settings-linux) ## 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/best-performance-settings.md
