    lsfg-vk

    Lossless Scaling Frame Generation on Linux

    ...Instead of relying on driver-specific or hardware-accelerated upscaling, this layer intercepts Vulkan API calls and injects frame interpolation on the fly, effectively producing smoother motion in supported games and applications by creating synthetic intermediate frames. It is structured as a modular codebase with separate components for the backend, configuration UI, CLI tooling, shared logic, and the core layer implementation. Although it targets Linux environments and handhelds like Steam Deck, it depends on an existing installation of Lossless Scaling on the system to provide its frame generation logic.
