This paper investigates enabling exclusive OpenGL driver usage in the Yuzu Nintendo Switch emulator on Android. We describe motivations for driver exclusivity (performance stability, reduced API translation overhead, predictable GPU behavior), design choices for integrating an exclusive OpenGL backend, implementation details adapting Yuzu's renderer and Android EGL/ANativeWindow stack, compatibility and security considerations, and an evaluation comparing performance, power, and compatibility against the existing Vulkan backend and Mesa/ANGLE-based OpenGL layers on representative devices. Results show scenarios where a tailored exclusive OpenGL path reduces frame time variance and simplifies shader management, while highlighting trade-offs in portability and driver lifecycle. yuzu android opengl driver exclusive
