Vulkan 1.4.308 Brings NVIDIA's Provisional Present Metering Extension

Written by Michael Larabel in Vulkan on 14 February 2025 at 06:14 AM EST. Add A Comment
Vulkan 1.4.308 was quietly released last week and besides a few fixes what makes it interesting is the provisional VK_NV_present_metering extension.

VK_NV_present_metering is a new provisional Vulkan extension from NVIDIA for evenly metering presents. Present Metering with VK_NV_present_metering aims to evenly pace out the next vkQueuePresentKHR presents to provide smoother pacing in applications with frame generation integrations.

Presumably NVIDIA is working on the VK_NV_present_metering extension for the likes of better DLSS 4 frame generation support with Vulkan or software like VKD3D-Proton going through Vulkan from Windows Direct3D 12 games. But for now VK_NV_present_metering is a provisional specification that isn't recommended for any production use.

More details on the Vulkan 1.4.308 changes and the Present Metering extension via GitHub.
