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 vs Lossless Scaling, DLSS, FSR and XeSS - [OptiScaler vs Lossless Scaling](https://optiscaler.ink/comparisons/optiscaler-vs-lossless-scaling) — A paid Steam app that scales and frame-generates almost any window from outside the game. Pick OptiScaler when a game exposes a supported temporal input and you want the real upscaler pipeline; pick Lossless Scaling for games with no usable input or when you cannot place files by the executable. - [OptiScaler vs native DLSS](https://optiscaler.ink/comparisons/optiscaler-vs-dlss) — NVIDIA's DLSS as the game itself ships it, with no translation layer. OptiScaler does not replace DLSS as a technology; it redirects DLSS (and FSR/XeSS) calls. Keep native DLSS when it already does what you want. - [OptiScaler vs native FSR](https://optiscaler.ink/comparisons/optiscaler-vs-fsr) — AMD FSR as the game itself ships it. Use OptiScaler to reach an FSR output a game did not ship, or to test FSR4 paths; native FSR needs no layer when it is already current. - [OptiScaler vs native XeSS](https://optiscaler.ink/comparisons/optiscaler-vs-xess) — Intel XeSS as the game itself ships it. OptiScaler's value is choice: the same game input can be tested against XeSS and FSR outputs without waiting for a game patch. - [OptiScaler vs FSR 3 in OptiScaler](https://optiscaler.ink/comparisons/fsr4-vs-fsr3-in-optiscaler) — The older FSR generation as an OptiScaler output. FSR4 is the quality target on supported hardware; FSR 3 remains the compatibility fallback. Always verify which one is actually active. - [OptiScaler vs FSR Frame Generation](https://optiscaler.ink/comparisons/optifg-vs-fsr-frame-generation) — Frame generation tied to the FSR pipeline. Both are experiments on top of a healthy base frame rate. Compare them in the same scene and keep the one with cleaner UI and latency. ## Comparisons: related searches - [OptiScaler vs Lossless Scaling](https://optiscaler.ink/keywords/optiscaler-vs-lossless-scaling) - [Lossless Scaling vs OptiScaler](https://optiscaler.ink/keywords/lossless-scaling-vs-optiscaler) - [OptiScaler or Lossless Scaling](https://optiscaler.ink/keywords/optiscaler-or-lossless-scaling) - [OptiScaler Frame Generation vs Lossless Scaling](https://optiscaler.ink/keywords/optiscaler-frame-generation-vs-lossless-scaling) - [OptiScaler vs DLSS](https://optiscaler.ink/keywords/optiscaler-vs-dlss) - [DLSS vs OptiScaler](https://optiscaler.ink/keywords/dlss-vs-optiscaler) - [OptiScaler vs FSR](https://optiscaler.ink/keywords/optiscaler-vs-fsr) - [FSR vs OptiScaler](https://optiscaler.ink/keywords/fsr-vs-optiscaler) - [OptiScaler vs XeSS](https://optiscaler.ink/keywords/optiscaler-vs-xess) - [OptiScaler DLSS to FSR](https://optiscaler.ink/keywords/optiscaler-dlss-to-fsr) - [OptiScaler DLSS to XeSS](https://optiscaler.ink/keywords/optiscaler-dlss-to-xess) - [OptiScaler Replace DLSS](https://optiscaler.ink/keywords/optiscaler-replace-dlss) - [OptiScaler Replace FSR](https://optiscaler.ink/keywords/optiscaler-replace-fsr) - [OptiScaler DLSS Input FSR Output](https://optiscaler.ink/keywords/optiscaler-dlss-input-fsr-output) - [OptiScaler FSR Input](https://optiscaler.ink/keywords/optiscaler-fsr-input) - [Best OptiScaler Output](https://optiscaler.ink/keywords/best-optiscaler-output) - [OptiScaler DLSS Input FSR Output 0.9.4](https://optiscaler.ink/keywords/optiscaler-dlss-input-fsr-output-0-9-4) - [OptiScaler DLSS to FSR 0.9.4](https://optiscaler.ink/keywords/optiscaler-dlss-to-fsr-0-9-4) - [OptiScaler DLSS to XeSS 0.9.4](https://optiscaler.ink/keywords/optiscaler-dlss-to-xess-0-9-4) - [How to DLSS vs OptiScaler](https://optiscaler.ink/keywords/how-to-dlss-vs-optiscaler) - [How to FSR vs OptiScaler](https://optiscaler.ink/keywords/how-to-fsr-vs-optiscaler) - [OptiScaler DLSS Input FSR Output Linux](https://optiscaler.ink/keywords/optiscaler-dlss-input-fsr-output-linux) - [OptiScaler DLSS to FSR Linux](https://optiscaler.ink/keywords/optiscaler-dlss-to-fsr-linux) - [OptiScaler DLSS to XeSS Linux](https://optiscaler.ink/keywords/optiscaler-dlss-to-xess-linux) - [OptiScaler How to DLSS Input FSR Output](https://optiscaler.ink/keywords/optiscaler-how-to-dlss-input-fsr-output) - [OptiScaler How to DLSS to FSR](https://optiscaler.ink/keywords/optiscaler-how-to-dlss-to-fsr) - [OptiScaler How to DLSS to XeSS](https://optiscaler.ink/keywords/optiscaler-how-to-dlss-to-xess) - [DLSS vs OptiScaler 0.9.4](https://optiscaler.ink/keywords/dlss-vs-optiscaler-0-9-4) - [FSR vs OptiScaler 0.9.4](https://optiscaler.ink/keywords/fsr-vs-optiscaler-0-9-4) - [How to Best OptiScaler Output](https://optiscaler.ink/keywords/how-to-best-optiscaler-output) - [OptiScaler FSR Input 0.9.4](https://optiscaler.ink/keywords/optiscaler-fsr-input-0-9-4) - [OptiScaler Replace DLSS 0.9.4](https://optiscaler.ink/keywords/optiscaler-replace-dlss-0-9-4) ## 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 FAQ: the official 20 questions, answered](https://optiscaler.ink/faq) - [OptiScaler guides: install, FSR4, Linux, performance and safety](https://optiscaler.ink/guides) - [OptiScaler vs Lossless Scaling](https://optiscaler.ink/comparisons/optiscaler-vs-lossless-scaling) - [OptiScaler vs native DLSS](https://optiscaler.ink/comparisons/optiscaler-vs-dlss) - [OptiScaler vs native FSR](https://optiscaler.ink/comparisons/optiscaler-vs-fsr) - [OptiScaler vs native XeSS](https://optiscaler.ink/comparisons/optiscaler-vs-xess) ## Download ZIP next to the game executable: [Download OptiScaler](https://optiscaler.ink/download) Markdown mirror: https://optiscaler.ink/comparisons.md
