Lossless Scaling 3.0 vs. 2.0 For ROG Ally

Lossless Scaling has always been a critical tool for ROG Ally users aiming to strike the perfect balance between performance and visual fidelity.

Lossless Scaling (LSFG) has been a frontrunner in this space, and the release of LSFG 3.0 marks a significant evolution.

This blog compares LSFG 3.0 with its predecessor, LSFG 2.0, highlighting key differences and improvements.

Key Improvements in LSFG 3.0

Lossless Scaling 3.0 Improvement #1 - Enhanced Quality

LSFG 3.0 introduces a new, efficient architecture that greatly improves motion clarity and smoothness:

• Reduced Flickering and Artifacts: The border artifacts and motion-related flickering seen in LSFG 2.0 have been significantly minimized.
• Improved Motion Clarity: Gamers can now enjoy smoother gameplay with less visual disruption during fast movements.

Lossless Scaling 3.0 Improvement #2 - Lower GPU Load

One of the standout achievements of LSFG 3.0 is its remarkable reduction in GPU load:

• 40% Lower GPU Load at X2 Multiplier: Compared to LSFG 2.0’s non-performance mode, LSFG 3.0 is far more efficient, particularly at higher multipliers.
• Over 45% Reduction for High Multipliers (Above X2): Gamers pushing their hardware to its limits will appreciate this significant improvement.
• Resolution Scale Feature: This feature allows further reductions in GPU load, aligning a 90% setting with LSFG 2.0’s Performance mode.

Lossless Scaling 3.0 Improvement #3 - Reduced Latency

Latency is critical for responsive gameplay, and LSFG 3.0 delivers notable advancements:

• 24% Better End-to-End Latency: Testing with the OSLTT tool (at 40 FPS, X2) shows a significant improvement compared to LSFG 2.0.

Lossless Scaling 3.0 Improvement #4. Unlocked Multiplier

For gamers with high refresh rate setups, LSFG 3.0 introduces an unlocked multiplier capped at X20, offering unparalleled flexibility:

• Recommendations for use:
  • Base Framerate: A minimum of 30 FPS is required, but 40 FPS or higher is preferred, with 60 FPS being ideal for the best experience.
  • Resolution Scaling for High Resolutions:
    • 75% for 1440p.
    • 50% for 4K.
  • High Refresh Rate Multipliers:
    • X5 for 240Hz setups.
    • X6 for 360Hz.
    • X8 for 480Hz.

How Does LSFG 2.0 Compare?

While LSFG 2.0 introduced notable improvements over its earlier versions, it falls short in several areas when compared to LSFG 3.0:

• Artifact Management: LSFG 2.0 reduced common issues like motion ghosting and edge distortion but still struggled with blurring and flickering in some cases.
• Performance Mode: LSFG 2.0’s Performance mode preserved efficiency but lacked the GPU optimization advancements now seen in LSFG 3.0.
• Increased GPU Load: LSFG 2.0’s non-performance mode was 1.5–2x more demanding, making LSFG 3.0’s 40–45% reduction a game-changer.

Conclusion: LSFG 3.0’s Superior Performance

LSFG 3.0 is a significant leap forward, delivering better quality, lower latency, and improved GPU efficiency compared to LSFG 2.0.

With its unlocked multiplier and enhanced architecture, it caters to gamers looking for smoother gameplay and optimal performance on high-refresh-rate setups.

Whether you're upgrading from LSFG 2.0 or exploring lossless scaling for the first time, LSFG 3.0 sets a new benchmark for scaling solutions.
