Lossless Scaling -lsfg 3- May 2026

LSFG 3 functions by intercepting the frame buffer output of a game or application. It analyzes two sequential frames and utilizes an Optical Flow algorithm to calculate the motion vectors of pixels between these frames.

| Setting | Recommendation for LSFG 3 | |---------|----------------------------| | Scaling Mode | Auto (or Custom if you need aspect ratio control) | | Scaling Type | LS1 or FSR – use LS1 for crisp pixel art/2D, FSR for 3D games | | Frame Generation | LSFG 3.0 (not 2.2 or Off) | | Mode | X2 (most stable), X3 / X4 if you have high base FPS (e.g., 75+ → 225+) | | Max Frame Latency | 1 or 2 (lower = better response, higher = smoother gen) | | Resolution Scale | 90-100% (lower = better perf but softer image) | | Cursor | Keep as is or hide if gets doubled | | Capture API | DXGI (most stable) – change to WGC if DXGI flickers | Lossless Scaling -LSFG 3-

Before diving into LSFG 3, it is important to understand the host application. Lossless Scaling is a $7 (or regional equivalent) application available on Steam. Unlike NVIDIA DLSS or AMD FSR, which require game integration, Lossless Scaling works as an overlay on any game or video. LSFG 3 functions by intercepting the frame buffer

It offers two primary functions:

Note: The tool captures your entire screen (or specific window) and applies scaling/frame generation live. LSFG 3 operates as an overlay application that

LSFG 3 operates as an overlay application that sits between the game and the Windows Desktop Window Manager (DWM).
