VKD3D-Proton Direct3D 12 to Vulkan: Version 3.0.1

Executive Summary

This is likely the last release before VK_EXT_descriptor_heap lands. There are some practical reasons why this is 3.0.1 instead of 3.1, but numbers don't really matter that much anyway. A ton of work on descriptor heaps have been happening in the background as well, but that is not included in this release. Features D3D12 view instancing is now experimentally supported. It is enabled for the one known game that requires it, Crimson Desert (1.04+).

Open Gaming Ecosystem & Proton Runtime Deep-Dive

From a graphics pipeline, kernel sub-system, and runtime compatibility perspective: - **Translation Efficiency:** Minimizing DirectX/Vulkan mapping overhead (DXVK, VKD3D-Proton) delivers deterministic frame times. - **Kernel Synchronization:** Integration of wineserver optimizations with fsync/futex primitives eradicates multi-threaded bottlenecks. - **Engine Neutrality:** Open engines like Godot provide a genuinely vendor-independent development target.

Impact on the Open Ecosystem

Solidifies Linux as an uncompromising, tier-one operating system for high-performance interactive 3D computing.
