Happy anniversary, LSFG!
LSFG 3 is built on a new, efficient architecture that introduces significant improvements in quality, performance, and latency.
Key improvements include:
- Better quality:
Reduced flickering and border artifacts, with noticeable enhancements in motion clarity and overall smoothness. - Lower GPU load:
A 40% reduction for X2 mode compared to LSFG 2 (non-performance mode). Over 45% reduction for multipliers above X2 compared to LSFG 2 (non-performance mode).
The "Resolution Scale" feature remains an excellent way to further reduce GPU load. For instance, setting it to 90% roughly aligns with the LSFG 2 "Performance" mode. - Improved latency:
Latency testing with the OSLTT tool (at 40 base FPS, X2) shows approximately 24% better end-to-end latency compared to LSFG 2. - Unlocked multiplier:
LSFG 3 also introduces an unlocked multiplier, now capped at X20. While this offers greater flexibility, the following recommendations apply for optimal results: Base framerate: A minimum of 30 FPS is required (40 FPS or higher is preferred, with 60 FPS being ideal) at 1080p.
For best overall experience, locking the game framerate is recommended. This helps to avoid 100% GPU load (reducing its impact on latency) and ensures smoother framepacing.
For higher resolution use at higher than recommended framerates or use the "Resolution Scale" option to downscale input to 1080p:
For 1440p, set it to 75%.
For 4K, set it to 50%. Higher multipliers (e.g., X5 or above) are best suited for high refresh rate setups, such as: 48 FPS × X5 for 240Hz.
60 FPS × X6 for 360Hz.
60 FPS × X8 for 480Hz.
