Lossless Scaling V3100 Portable Guide

Important Disclaimer:
Lossless Scaling is a paid software on Steam. Distributing or using a "portable" cracked version is piracy and violates the developer's rights. This guide assumes you have legitimately obtained a portable version (e.g., from a trusted friend who owns a license and created a portable copy for personal use on different PCs, or an official portable build if provided). I do not condone software piracy.

Step 3: Using Lossless Scaling (Portable)

There are two main workflows:

Why Portable?

The official installer version places drivers and hooks into your system. The portable variant offers distinct advantages: lossless scaling v3100 portable

| Aspect | Installer | Portable | |--------|-----------|----------| | Admin rights | Required | Not required | | Registry writes | Yes | None | | USB drive ready | No | Yes (run from any folder) | | Multiple versions | Conflicts possible | Keep v3.1.0 and v2.x side-by-side | | Uninstall | Run uninstaller | Delete folder | Important Disclaimer: Lossless Scaling is a paid software

Recommended Settings for LSFG (Frame Gen)

  1. Cap Your FPS: The most critical step. You must cap your game's internal FPS slightly below your monitor's refresh rate divided by your multiplier.
    • For 60Hz Monitor wanting 60FPS output: Cap game at 58-59 FPS (using 1x mode is better here, or use 2x if base is 30).
    • For 144Hz Monitor wanting 120FPS: Cap game at 60 FPS (2x mode).
    • Tool: Use RivaTuner Statistics Server (RTSS) or the in-game limiter for the most stable frame times.
  2. Disable In-Game VSync: Let Lossless Scaling handle the synchronization, or use the "Triple Buffering" option within LS.
  3. UI Detection: Frame generation often creates artifacts (smearing) on HUDs and menus. Some games allow you to adjust UI opacity, but generally, this is a trade-off for the increased FPS.

System Requirements

  • OS: Windows 10 1903+ or Windows 11 (64-bit)
  • GPU: DirectX 11/12, Vulkan, or OpenGL support
    • For LSFG 3.0: Recommend NVIDIA GTX 1060+ / AMD RX 580+
  • RAM: 4 GB minimum
  • Portable mode needs: Write access to its own folder (no registry changes, no admin required)

3. Real-time Capture & Scaling

  • Works on any window: emulators (PCSX2, Cemu, Yuzu), video players (VLC), legacy DirectX 8/9 games, and even desktop applications.

How to Use (Portable Workflow)

  1. Extract the portable archive to a folder, e.g., D:\Tools\LosslessScaling_v3.1.0
  2. Launch LosslessScaling.exe (no installation prompt)
  3. Configure:
    • Scale Factor: 2x, 3x, or Custom (e.g., 720p → 1080p)
    • Frame Generation: LSFG 2.2 (select 2x, 3x, or 4x)
    • Capture API: DXGI (for most modern games) or GDI (for old 2D)
    • Cursor: Hide or keep visible
  4. Hotkey (default: Ctrl+Alt+S): Start scaling on the active window.
  5. Stop: Same hotkey or close the overlay.
