Windows 10/11, a GPU that supports DirectX 11 or 12 (integrated graphics work, but a dedicated GPU is better).

Press the “Scale” button (or your assigned hotkey – default Ctrl + Alt + S ). You have 5 seconds to click back into your game window. You will see a green "Active" indicator.

Run your game in Windowed or Borderless Windowed mode. Lossless Scaling cannot hook into exclusive fullscreen easily.

"My GPU usage is 99% and the app crashes." Fix: Lower your game’s graphics settings. Lossless Scaling needs about 10-15% GPU headroom to generate frames. Cap your base FPS. Who Is This For? (Use Cases) 1. The Retro Gamer Playing Fallout: New Vegas or Oblivion ? Their engines break above 60 FPS. Use Lossless Scaling to keep the game logic at 60 but visually render at 120. No physics explosions. 2. The Emulator Enthusiast Zelda: Tears of the Kingdom on Yuzu/Ryujinx runs at 30 FPS. LSFG 2.0 doubles it to 60 with minimal artifacts. v3.1.0.0 handles the UI cross-progression better than ever. 3. The Budget PC Owner You have integrated graphics. You want to play Baldur’s Gate 3 at 720p/40fps. Scale via FSR to 1080p, then generate to 80fps. It’s witchcraft. 4. The Competitive Purist? No. Stay away. Turn it off for Apex Legends or The Finals . The input lag, however improved, will lose you fights. The Future: What v3.1.0.0 Teases The developer, THS, has hinted that v3.1.0.0 lays the groundwork for adaptive frame generation —where the multiplier changes on the fly based on motion complexity. Furthermore, community modders have discovered strings in the code referencing "LSFG 3.0" and "Per-application profiles."

At the price of a sandwich, Lossless Scaling v3.1.0.0 offers a utility that should be in every PC gamer’s toolkit. It transforms low-FPS experiences into playable ones, breathes life into emulated classics, and future-proofs your older titles for high-refresh-rate monitors.

For now, Lossless Scaling v3.1.0.0 is the gold standard for universal frame smoothing. Yes. Without hesitation.
