VKD3D-Proton 2.9 “Greatly” Reduces System Memory Requirements, Improves CPU Performance
This, along with plenty of bug fixes.
VKD3D-Proton 2.8 Reduces CPU Overhead, Adds Last-Minute Fixes for The Witcher 3 Next-Gen Upgrade
VKD3D-Proton – the layer responsible for translating DX12 calls to Vulkan, and an essential part of Proton – version 2.8 just released, and “rolls up some significant new developments before the holidays.”
First of all, 2.8 adds support for the VK_EXT_descriptor_buffer extension. This “removes a ton of CPU overhead.” This will particularly benefit desktop users who are on NVIDIA, Intel, Turnip, and “other AMD driver implementations” that are not pertaining to the Steam Deck.
VKD3D-Proton 2.7 ‘Fixes Many Previously Unsolvable Issues,’ Improves GPU Performance
An exciting new update has landed for vkd3d-proton. For those who aren’t aware, vkd3d-proton is a part of what makes up Proton, and “aims to implement the full Direct3D API on top of Vulkan.” It probably won’t be long before Proton Experimental or GE-Proton picks up this update. When it does, we will be seeing lots of benefits.
So first off, we have an improved pipeline cache. This release incorporates an “internal ‘magic’ disk cache to enable SPIR-V caching for all games.
