PB drivers are a superset of the NVIDIA Studio Drivers and provides all the benefits of the Studio Driver of the same version, in addition to NVIDIA RTX-specific enhancements and testing. PB drivers are designed and tested to provide long-term stability and availability, making these drivers ideal for enterprise customers and other users who require application and hardware certification from ISVs and OEMs respectively.

Release 460 is a 'Production Branch’ (PB) release. The new branch name will now allow driver types to be consistently referenced across other enterprise GPU products as well, such as Data Center GPUs. The driver branch name will also transition from 'Optimal Driver for Enterprise' to 'Production Branch.' All the same enterprise attributes of the driver branch will remain. These new drivers will not only deliver the latest features and improvements for NVIDIA RTX GPUs, but also for current and previous generation Quadro GPUs.

NVIDIA RTX Enterprise drivers will continue to provide users with the same level of enterprise-class quality, reliability, performance, and security as previous Quadro drivers. With the introduction of NVIDIA RTX products powering the next generation of professional visual, compute, and AI platform solutions for the enterprise, the Quadro driver will be transitioning to the NVIDIA RTX Enterprise brand to better align with new and future products.
