1. Executive Summary
Lossless Scaling v2.1.1 is a utility application designed to scale game windows or any application to full screen using high-quality algorithms, without introducing input lag typical of traditional bilinear or bicubic scaling. Version 2.1.1 represents a mature build in the v2.x lifecycle, focusing on stability, reduced overhead, and expanded compatibility with modern graphics APIs (DirectX 12, Vulkan). It is widely used for retro gaming, low-resolution indie titles, and improving performance by rendering at a lower internal resolution before scaling up. Technical Report: Lossless Scaling v2
