01.Introduction: Black Magic?
Lossless Scaling captures the game window and inserts fake (interpolated) frames between real frames using lightweight AI.
If your game runs at 30fps, it generates 1 fake frame for every real one -> 60 visual fps.
If you use X3 mode -> 90 visual fps.
Don't do it Manually.

02.Chapter 1: Mandatory Configuration
The Game
1. The game MUST be in Windowed Mode or Borderless Windowed. The app cannot capture Exclusive Fullscreen.
2. Lock the game's FPS (using RivaTuner or VSync) at a stable value your GPU can handle (e.g., 30fps or 60fps). If the FPS varies too much, LSFG creates horrible artifacts.
03.Chapter 2: Configuring the App
- Scaling Mode: Auto (Aspect Ratio).
- Scaling Type:
LS1 (Performance): Lightweight and sharp.
AMD FSR: Good for upscaling low resolutions.
Off: If you are already at native resolution and just want frame gen, leave it Off.
- Frame Generation: LSFG 2.1 (The current best).
Mode: X2 (Doubles) or X3 (Triples). X3 adds significant latency; use it only in slower-paced RPGs.
04.Chapter 3: Applying (Scale)
1. Configure the app.
2. Click the blue "Scale" button.
3. You have 5 seconds to click on the game window.
4. The screen will flicker and return to full screen with fluid frames.
Shortcut: Ctrl+Alt+S.
A1.Chapter 4: Reducing Latency
Generating frames takes time (ms). The game appears to run at 60fps, but the input lag is that of 30fps (or worse).
- Use Nvidia Reflex in-game if available.
- Enable "Allow Tearing" in Lossless Scaling if you don't mind screen tearing (reduces lag).
- Mouse: Increase your DPI.
- Do not use LSFG in competitive games (CS2/Valorant). It's intended for Single Player games.
A2.Chapter 5: Emulators (Yuzu/Cemu)
Perfect for emulation.
Zelda TOTK locked at 30fps on Yuzu?
Enable LSFG X2.
Visually it becomes 60fps. The camera fluidity is incredible.
Since emulators already have natural input lag, the extra latency is less noticeable.
A3.Chapter 6: Watching Videos (60fps Anime)
You can use it in Chrome/VLC!
Open an anime or movie on YouTube. Apply Lossless Scaling.
The video will play with interpolation (Soap Opera Effect). Some users love it.
A4.Chapter 7: Capture API (DXGI vs WGC)
In Settings > Capture API.
- DXGI: Default, faster.
- WGC (Windows Graphics Capture): Use if DXGI results in a black screen or fails to capture game overlays (menus).
Chapter 8: Ghosting
LSFG can leave trails on the interface (HUD) if it's static and the background moves quickly.
LSFG 2.1 has significantly improved this, but it still happens. It's the price to pay for "magical" performance.
Chapter 9: GPU Load
The app uses the GPU to generate frames. If your GPU is already at 100% running the game, Lossless Scaling will lag.
You need to leave some GPU headroom (limit game FPS to use about 80-90% of the GPU) for the app to function properly.
Chapter 10: Free Alternatives? (Magpie)
There is Magpie (Open Source), but it focuses on FSR (Upscaling) and doesn't have Frame Generation nearly as good as the paid LSFG.
Don't do it Manually.
