Advanced Lossless Scaling fork: boost FPS, enable Frame Gen & upscale any game.

Maximize your gaming performance. This highly optimized Lossless Scaling fork is designed to boost FPS, minimize input lag, and seamlessly upscale any PC game while bringing advanced frame generation capabilities to all GPUs.

This project is a custom fork of the popular Lossless Scaling utility. It aims to provide gamers with a powerful, accessible tool to upscale windowed games to full screen using state-of-the-art spatial scaling algorithms and optical flow frame generation.

Whether you are trying to squeeze extra frames out of an integrated GPU, playing an older game that doesn't support modern upscaling natively, or looking to utilize Frame Generation on unsupported hardware, this tool has you covered.

• Universal Frame Generation (LSFG): Generate high-quality intermediate frames to double or triple your framerate in almost any game, regardless of your GPU brand.
• State-of-the-Art Upscaling: Includes support for modern algorithms like AMD FSR, NVIDIA NIS, xBR, Anime4K, and custom LS1 algorithms.
• Hardware Agnostic: Works seamlessly across NVIDIA, AMD, and Intel graphics cards.
• Low Input Latency: Carefully optimized pipeline to ensure the generated frames do not compromise your gameplay responsiveness.
• Plug & Play: No game modifications or injections required.

• OS: Windows 10 / Windows 11 (64-bit) [Currently Windows-only]
• GPU: Any DirectX 11 / Vulkan compatible graphics card (Intel, AMD, NVIDIA)
• Display: A monitor supporting the desired output resolution and refresh rate.

Note: Linux and macOS are not supported in the current build, but cross-platform compatibility is planned for future releases.

You can install this utility in two ways, depending on your preference. Both versions are available on the Releases page.

1. Download the latest LosslessScaling-Installer-vX.X.X.exe from the Releases tab.
2. Run the executable and follow the on-screen instructions.
3. Launch the app from the Start Menu or Desktop shortcut.

1. Download the LosslessScaling-Portable-vX.X.X.zip archive.
2. Extract the contents to a folder of your choice (e.g., C:\Games\LosslessScaling).
3. Run Main.exe to start the application. No installation required.

1. Launch the Lossless Scaling application.
2. Configure your desired settings (Select Scaling Type, Sharpness, and enable/disable Frame Generation).
3. Launch your game and set its display mode to Windowed or Borderless Windowed at a resolution lower than your native monitor resolution.
4. Focus on the game window and press the default hotkey (Ctrl + Alt + S).
5. Enjoy the boosted performance and upscaled visuals!

(Tip: You can customize the hotkey and scaling behavior directly in the app settings).

• Core upscaling and frame generation pipeline optimization.
• Standard Windows Installer and Portable ZIP releases.
• UI/UX overhaul for better accessibility.
• Multi-monitor support enhancements.
• Investigate cross-platform support (Linux / Proton compatibility).

This project is a fork based on the original concepts of the Lossless Scaling community. Huge thanks to all open-source contributors who made the upscaling algorithms (like FSR and Anime4K) freely available.
