Technical deep dive

How Lossless Scaling Works: Architecture & Performance

Understanding the underlying technology helps you optimize settings for your specific hardware and use case.

LSFG Frame Generation Pipeline

Lossless Scaling Frame Generation (LSFG) operates as a post-processing layer that intercepts rendered frames before they reach your display. Unlike DLSS or FSR, which require game engine integration, LSFG works at the compositor level using DirectX, Vulkan, or OpenGL hooks.

1.

Frame Capture

Captures rendered frames at native resolution from the game's output buffer

2.

AI Interpolation

Uses neural network models to generate intermediate frames between consecutive frames

3.

Upscaling & Enhancement

Scales frames to target resolution and applies sharpening filters for clarity

4.

Frame Pacing

Synchronizes output with display refresh rate using VRR-aware timing algorithms

Integer Scaling Algorithm

Integer scaling multiplies each pixel by a whole number (2x, 3x, 4x) without interpolation, preserving the original pixel art aesthetic. This is crucial for retro games, pixel art titles, and maintaining UI clarity.

Perfect for:

Classic 2D platformers and RPGs
Pixel art indie games
Text-heavy applications
Handheld device emulation

Technical benefits:

Zero interpolation artifacts
Minimal GPU overhead (~2-5%)
Perfect pixel alignment
Maintains original aspect ratios

Pro tips & tricks

Advanced Optimization Techniques

Expert-level tips to squeeze maximum performance and quality from Lossless Scaling.

Reducing Input Latency

• Enable "Low Latency Mode" in NVIDIA Control Panel or AMD Software for competitive games
• Use Latency Sync instead of traditional V-Sync to minimize input delay
• Set "Max Pre-rendered Frames" to 1 in NVIDIA Control Panel
• Disable Windows Game Mode if you experience stuttering (Settings → Gaming → Game Mode)
• Use RivaTuner Statistics Server with scanline sync for frame-perfect timing

Minimizing Ghosting Artifacts

• Use Quality mode instead of Turbo for games with fast camera movement
• Reduce sharpening to 0.25-0.35 if you notice trailing artifacts
• Disable in-game motion blur and depth of field effects
• Ensure base FPS is stable (60+ for Quality, 90+ for Turbo) before enabling LSFG
• Update to latest Lossless Scaling version for improved ghosting filters

HDR Optimization

• Run Windows HDR Calibration app before using Auto HDR Fix mode
• Set HDR brightness to match your display's peak brightness (nits)
• Use Auto HDR Fix for UE4/UE5 games experiencing highlight clipping
• Adjust tone mapping curve in Lossless Scaling settings for HDR1000 displays
• Test HDR settings in both SDR and HDR content to ensure consistency

Streaming & Recording Setup

• Use Lossless Scaling OBS filter for 720p→1080p upscaling during streams
• Set OBS canvas to 1080p and game capture to 720p for optimal GPU usage
• Enable Dynamic Bitrate in OBS to prevent dropped frames during intensive scenes
• Use NVENC (NVIDIA) or AMF (AMD) encoding with the LS filter for best quality
• Assign hotkeys to toggle filters during live streams (default: Alt+Shift+U)

Frequently asked questions

Everything you need to know

Answers compiled from losslessscaling.com, community Q&As, and GitHub discussions so you always quote official statements.

Does Lossless Scaling work with Easy Anti-Cheat titles?

Yes. LS runs as an overlay and does not inject DLLs into the game process, so EAC/BattlEye titles remain compliant. Launch the game first, then enable scaling.

Do I need a modern GPU to use LSFG?

LSFG is optimized for RTX 2000+ or Radeon 6000+, but classic scaling modes still work on GTX 10-series hardware (without frame generation).

Is it safe for esports broadcasts or tournaments?

Yes. Communities such as Valorant sim racing leagues rely on LS because it enhances resolution outside the game and never edits game files.

How do I get beta builds or earlier fixes?

Join the official Discord via losslessscaling.com and grab the "Beta Tester" role, or follow the beta branch on GitHub for early binaries.

Can I use Lossless Scaling with multiple monitors?

Yes, Lossless Scaling supports multi-monitor setups. You can scale games on your primary display while using other monitors normally. Set the target resolution to match your primary monitor's native resolution for best results.

Does LSFG work with ray tracing enabled?

Yes, LSFG works with ray tracing. However, you may need to use Quality mode instead of Turbo mode, as ray tracing significantly reduces base FPS. The frame generation will still provide a noticeable boost, typically 40-60% FPS increase.

How much GPU overhead does Lossless Scaling add?

LSFG typically adds 15-25% GPU overhead, while basic scaling modes add only 2-5%. The overhead is generally acceptable given the FPS gains, especially when upscaling from lower resolutions. Monitor GPU usage with tools like MSI Afterburner to ensure you're not bottlenecking.

Can I use Lossless Scaling with DLSS or FSR at the same time?

While technically possible, it's not recommended. Using both simultaneously can cause visual artifacts and increased latency. Instead, use Lossless Scaling for games without DLSS/FSR support, or use LSFG's frame generation with DLAA (DLSS Anti-Aliasing) for the best quality.

What's the difference between Quality and Turbo mode in LSFG?

Quality mode is optimized for base FPS between 60-90, providing smoother frame generation with fewer artifacts. Turbo mode activates when base FPS exceeds 90, using a faster algorithm that may introduce slightly more ghosting but provides better performance. Choose Quality for stability, Turbo for maximum FPS.

Does Lossless Scaling work with VR headsets?

Lossless Scaling is designed for traditional displays and does not officially support VR headsets. Using it with VR may cause motion sickness, latency issues, or visual artifacts. It's recommended to use VR-specific upscaling solutions provided by VR headset manufacturers.

How do I update Lossless Scaling?

Lossless Scaling can be updated by downloading the latest version from this website. Check for updates in the application settings, or download the latest version directly. Always backup your profiles before updating to avoid losing custom configurations.
