Free Lossless: Open AI Frame Generation

Free Lossless is a high-performance, non-intrusive Frame Generation tool for Windows. It enhances game fluidity by creating synthetic frames using AI, similar to technologies like DLSS 3 or LSFG, but without requiring any modification to the game's code.

How it works (Simple words)

Unlike most frame generation tools that need to be "inside" the game (using its engine data), Free Lossless works from the outside:

1. High-Speed Capture: It looks at your screen and "captures" the game window at high speed (using DXCAM or BitBlt).
2. AI Interpolation: It uses the RIFE AI model to analyze the movement between two real frames and calculates exactly how the intermediate frame would look.
3. Transparent Overlay: It creates a completely transparent window (an "overlay") that sits on top of your game. It displays the original and the new AI-generated frames in perfect sequence.

No Injection: Since it doesn't inject files, hook into the game process, or modify the GPU pipeline, it is extremely safe and compatible with almost any application.

Why use it?

• No Game Access: Perfect for older games, emulators, or modern titles that don't support DLSS/FSR frame generation natively.
• Engine Independent: It works regardless of the graphics engine (DirectX, OpenGL, Vulkan).
• Lossless Approach: No need to lower your internal game resolution unless you want extra performance.

1. Create a Virtual Environment

python -m venv venv

2. Activate the Environment

.\venv\Scripts\Activate.ps1

3. Install Dependencies

pip install -r requirements.txt

4. Run the Application

python main.py

Building the Executable

To create a standalone .exe:

python build_app.py

The executable will be generated in the dist folder and will be around 2.63 GB.
