Tutorial

• 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.

• Introduced a new "Resolution Scale" option for LSFG. This feature allows input frames to be processed at a reduced resolution while generating output at the original resolution. For example, when playing at 1440p, setting the scale to 50% enables LSFG to generate 1440p output from a 720p input. This provides a performance boost with only a minor quality trade-off (depending on the game). Note that this is not related to image scaling; rather, it reduces the amount of information available to LSFG for motion estimation.
• LSFG 1.1 has been fully replaced by LSFG 2.3 and is no longer available. For instance, at a resolution scale of 90%, LSFG 2.3 Performance is both faster and of higher quality. If you still wish to use LSFG 1.1, LS 2.11 remains available in the Betas section on Steam.
• Introduced SGSR v1, a highly lightweight spatial upscaler. For more details, visit the official page: https://github.com/SnapdragonStudios/snapdragon-gsr.
• With the latest Windows 11 24H2 update, Microsoft changed how the Desktop Duplication API (DXGI) functions, making it heavily reliant on MPO (Multiplane Overlay) support. Without MPO, DXGI cannot reliably distinguish between updates from game window and the LS window when both are displayed on the same monitor. This prevents it from capturing only new frames, thereby breaking the existing framepacing algorithm. MPO support varies between systems, and there is no definitive way to determine why it is supported on some setups and not on others. You can use dxdiag to check if your system has MPO support. In some cases, you might be able to work around the issue. For instance, if you have two monitors connected, disconnecting one may force the remaining monitor to support MPO. As of the 24H2 update, DXGI is no longer a reliable capture method unless Microsoft changes its approach or Nvidia and AMD improve MPO support in their drivers. On the other hand, Microsoft has addressed a five-year-old bug in the Windows Graphics Capture (WGC) API, which previously prevented it from capturing only new frame updates. Starting with version 24H2, WGC now works as expected for the most part. Essentially, DXGI and WGC have switched roles in this update. WGC capture in LS has been updated with a new framepacing algorithm to replace DXGI on newer systems while maintaining the same behavior as before on older systems. DXGI continues to function normally up to version 23H2, but beyond that, it depends on MPO support. While WGC generally offers some advantages over DXGI, such as allowing LS to be recordable by most tools, it also has drawbacks without MPO support. Specifically, in games where a hardware cursor is displayed and VRR is enabled, WGC disables independent flip mode globally. This can lead to issues with LS and VRR functionality. Starting with Windows 11 24H2, MPO support becomes highly desirable. We can hope that future updates from Microsoft, Nvidia, and AMD will address these challenges. Notably, there have been reports that DXGI is functioning correctly again on the Windows 11 Dev branch.

What's new:

UI:

• Completely new UI with themes support;
• Support for game profiles: you can still use the hotkey or scale button - game profile will be applied automatically, or you can use the auto scale option to let the game window to be scaled automatically whenever it is activated (including window activation when the game starts);
• Ability to choose preferred GPU (may be useful for laptops);
• Option to run as administrator;
• Option to start minimized at Windows startup;
• Option to minimize to tray;
• New settings storage;
• Localizations for:
  • French
  • German
  • Portuguese, Brazilian
  • Russian
  • Spanish
  • Turkish

Core:

• The latency has been improved. The "Low Latency" option has been removed as unnecessary;
• LS will create a driver profile for itself on first launch to set "Prefer Maximum Performance" (NVIDIA only, relaunch required to apply profile);
• FSR updated to 1.0.2 version, NIS updated with a fix;
• Got rid of the old Windows API which was used for integer and nearest neighbor scaling. Now that uses modern way of capturing and scaling which paves the way for adding a large number of new scalers for pixel art graphics. The rendering options are now the same for all types of scaling.

What has been removed:

• Shortcut support;
• Alignment option;
• Hide cursor option;
• Multi-display option;
• Anti-aliasing option;
• Low latency option.
