Live Background Removal Lite
A high-performance, crash-resistant OBS plugin for real-time background removal.Live Background Removal Lite is a complete rewrite of the popular obs-backgroundremoval tool, engineered from scratch to prioritize stability, compatibility, and smart resource management.
Unlike other AI plugins that monopolize your GPU, this plugin follows a "Gaming-First" philosophy. It intelligently offloads AI inference to the CPU while using the GPU only for lightweight post-processing. This ensures your stream stays smooth and your games keep their max FPS.

Under the Hood: The Smart Hybrid Pipeline
We use a sophisticated CPU/GPU Hybrid Pipeline to achieve efficiency:- Smart Motion Detection (GPU): If you aren't moving, the plugin pauses heavy calculations to save power.
- Constant-Cost AI (CPU): AI runs at a fixed low resolution on the CPU, ensuring consistent performance.
- Fast Guided Filter (GPU): We use a custom shader to upscale the mask, giving you crisp edges and high-quality results without the heavy GPU load.
