Lossless Scaling Portable Updated -
Limit your game's internal frame rate to match half of your monitor's total refresh rate. If you want to optimize your setup further, let me know: What or handheld device you are using The specific game you want to upscale Your monitor's native resolution and refresh rate
Toggle to "LSFG" if you need a major frame rate boost.

By default, Lossless Scaling is distributed via Steam. However, setting it up as a portable application offers massive advantages for mobile gamers, especially those using devices like the Steam Deck (running Windows), ASUS ROG Ally, Lenovo Legion Go, or a work-and-gaming laptop crossover. The Benefits of Portability
The utility will capture the lower-resolution window and scale it cleanly to fill your entire monitor. Best Practices for Frame Generation (LSFG) lossless scaling portable updated
This is the flagship feature of the recent updates (specifically versions 2.0 through the current 2.8+ updates), and it works exceptionally well with the portable nature of the software.
Users can now go beyond doubling frames ( ); the software supports and even multipliers, though is still recommended to avoid excessive visual artifacts.
| Setting | Recommendation | | :--- | :--- | | | Auto (Fullscreen) | | Scaling Type | FSR (for 3D games) / Integer (for pixel art) | | Frame Generation | LSFG 3.0 (X2 mode for most cases) | | Resolution Scale | 50-75% (to reduce GPU load) | | Max Frame Latency | 2 (for portable lower-power GPUs) | | Cursor Capture | On (prevents cursor fleeing on multiple monitors) |
This comprehensive guide covers everything you need to know about the updated portable version of Lossless Scaling, exploring its core features, setup process, and optimal settings. What is Lossless Scaling Portable? Limit your game's internal frame rate to match
Here is everything you need to know about setting up, optimizing, and utilizing the updated version of Lossless Scaling in a fully portable format. What is Lossless Scaling?

As of late 2025 / early 2026, the current stable version is (or newer). Here is what you get in the updated portable version:
Portable builds often allow you to swap out core files easily to test beta algorithms. How Lossless Scaling Works However, setting it up as a portable application

Select your preferred (FSR is recommended for modern 3D games).
Set the display mode to or Borderless Windowed . (The tool cannot scale exclusive fullscreen applications).
The crown jewel of the updated version is its proprietary Frame Generation algorithm (LSFG). Unlike hardware-gated solutions like NVIDIA DLSS 3, LSFG is completely agnostic. It works on any GPU—Intel, AMD, or NVIDIA. The updated version introduces LSFG 2.1, which dramatically reduces processing overhead, cuts down on visual artifacts (ghosting), and offers a 3X frame generation mode (tripling your perceived frame rate). 2.
