NVIDIA released the GeForce 376.80 Beta drivers. These drivers are being released exclusively through the Vulkan developer support channel, and come with bug fixes for the company’s implementation of Vulkan API support. The change-log is limited to just “bug fixes,” and the drivers are not WHQL-signed. If you’re gaming on the Vulkan API, on titles such as “Doom,” “Ashes of the Singularity,” etc.
You can download the new GeForce 376.80 Beta Vulkan Support driver from the NVIDIA Vulkan Support site.
