NVIDIA Ships Fixes For Descriptor Heaps, More Vulkan Performance Optimizations
NVIDIA has released new Vulkan developer beta drivers for both Linux and Windows, featuring improvements and fixes for descriptor heap support. The update includes performance optimizations for shader operations and enables external buffers to be bound to host-visible, device-local memory. These changes aim to enhance efficiency and improve compatibility with technologies like Steam Play (VKD3D-Proton).
- ▪NVIDIA released the 595.44.06 beta driver for Linux and 595.46 for Windows with Vulkan optimizations.
- ▪The update improves support for VK_EXT_descriptor_heap, which helps reduce CPU overhead and benefits Steam Play (VKD3D-Proton).
- ▪Vulkan descriptor heaps allow explicit management of descriptor memory, a modern efficiency enhancement.
- ▪The new drivers include performance gains for shader operations on BDA data.
- ▪External buffers and images can now be bound to host-visible, device-local memory in this release.

NVIDIA Ships Fixes For Descriptor Heaps, More Vulkan Performance Optimizations Written by Michael Larabel in NVIDIA on 2 May 2026 at 06:41 AM EDT. 1 Comment NVIDIA on Friday released the 595.44.06 beta driver build as their newest Vulkan developer beta for Linux. This was joined by the NVIDIA 595.46 Windows Vulkan beta and there are performance improvements in tow and more work on their descriptor heaps support. The NVIDIA R595 Linux driver is big for introducing VK_EXT_descriptor_heap support. Vulkan descriptor heap functionality allows for explicit management of descriptors and the memory used for descriptors. This extension is important for improving the Steam Play (VKD3D-Proton) experience, can help reduce CPU overhead, and all around a modern efficiency win.
