The branch of the NVIDIA driver to use. Note: if hardware.nvidia.package is set, it overrides this option. Commonly interesting branches for end users: production, new_feature, beta: NVIDIA’s official production / new feature / beta release branches. stable: The default; the highest stable version. latest: Whichever is newer of production and new_feature. bleeding_edge: Whichever is newer of latest and beta. legacy_580: The long-lived 580 series (LTSB), for GPUs that newer driver branches no longer support (often Maxwell through Volta; roughly GeForce GTX 9xx through 10xx, plus rare Volta cards like TITAN V). vulkan_beta: The Vulkan developer beta driver, for users interested in testing new Vulkan features.
