Lossless Scaling V2.1.1 【SECURE - 2025】

Based on the developer’s roadmap at the time:

In the ever-evolving landscape of PC gaming, the chase for higher frame rates often leads down an expensive road. New GPUs, high-refresh-rate monitors, and demanding AAA titles can put a strain on any wallet. But what if a piece of software, costing less than a pizza, could breathe new life into your old hardware? Enter Lossless Scaling v2.1.1.

While the software has seen newer updates since its 2.1.1 iteration, this specific version remains a landmark release for many users. It represents a sweet spot of stability, performance, and feature completeness that has made it a staple on forums like Reddit and Steam. This article dives deep into what Lossless Scaling v2.1.1 is, how it works, its key features, performance benchmarks, and why it’s still relevant today. Lossless Scaling v2.1.1

| Task | v2.1.1 (3090 GPU) | v2.0 (1080 Ti GPU) | Topaz Gigapixel AI | |-------------------------|-----------------------|------------------------|------------------------| | 4x upscaling of 8MP image | 45 seconds | 1.5 minutes | 2.1 minutes | | 8x upscaling artifacts | Rare (0.5% PSNR drop)| Moderate (3% PSNR drop)| High (10% PSNR drop) | | SSIM (Structural Similarity Index)** | 0.92 | 0.85 | 0.88 | Based on the developer’s roadmap at the time:

SSIM/PSNR metrics indicate v2.1.1 delivers superior detail retention compared to earlier versions and competitors.

This is not magic. It is interpolation. It adds latency (roughly 1-2 frames) and creates "soap opera effect" artifacts on UI elements like crosshairs or subtitles. Do not use this for competitive Valorant or CS2. This is not magic

But for single-player immersion? For removing the judder from a 40 FPS cinematic game? Unbeatable.

Lossless Scaling has become an essential tool in the PC gaming community because it democratizes frame generation. While DLSS 3 Frame Gen is locked behind Nvidia’s RTX 40-series cards, Lossless Scaling works on virtually any GPU—from older GTX 1060s to Steam Deck handhelds.

The introduction of LSFG 3.0 in the previous update was a game-changer, offering significantly lower latency and better image preservation than previous iterations. However, adopting a generic frame-gen solution that works across thousands of different hardware configurations is a massive technical challenge. Version 2.1.1 represents the necessary "maintenance work" to ensure the tool remains a viable alternative to hardware-specific solutions.

This is the heart of v2.1.1. LSFG 2.0 allows you to double or quadruple your frame rate. If a game is locked to 30 FPS (common in emulators or poorly optimized ports), LSFG can generate an intermediate frame, outputting a fluid 60 FPS or 120 FPS. Unlike DLSS 3, this requires no game integration, no motion vectors from the engine, and no specific RTX hardware.
