optiscaler/OptiScaler
OptiScaler
OptiScaler is a DirectX graphics middleware and temporal upscaler wrapper designed to intercept graphics API calls. It functions as a system for replacing native temporal anti-aliasing and upscaling technologies with alternative scaling methods and frame generation interop to improve resolution and performance.
The project distinguishes itself by enabling modern high-resolution upscaling and frame generation in games built for legacy rendering standards. It includes a framework for importing low-latency graphics plugins and utilizes an interception layer to replace existing frame interpolation methods or add them to unsupported games.
The software covers a broad range of graphics rendering enhancements, including the ability to tune upscaling quality, mitigate HUD ghosting through UI-boundary isolation, and reduce input latency. It also provides system-level capabilities for modifying engine variables and patching libraries to ensure stability across different operating systems.

How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
