DirectX Engine

D3D12 Rendering Backend

Replaces OpenGL/Vulkan with a native C++ D3D12 rendering backend by implementing Mojang's official GpuBackend / GpuDeviceBackend interface. Zero custom render loops — fully takes over the official Minecraft rendering pipeline.

Features

• Full render pipeline takeover：Mixin-based API selection override, no RenderSystem rewrite, relies on Minecraft's official rendering engine
• Complete shader compilation chain：GLSL → SPIR-V (shaderc) → HLSL SM5.1 (spvc) → DXBC (D3DCompile)，supports all official shaders
• 4-stage self-test：Resource creation / command submission / pipeline compilation / swapchain verification — auto-fallback to OpenGL on any failure
• Async rendering infrastructure：Per-worker mirror descriptor heaps + Bundle recording + Fence event-driven sync (ASYNC-01/03/04/05 fixed)
• AA mode selection：None / FXAA / SMAA / TAA, settings persisted to config/gl4dx12.properties

What's Fixed

System Requirements

• OS：Windows 10 (1809+) / Windows 11
• GPU：DirectX 12 Feature Level 11_0 or above (DX12 recommended)
• RAM：8 GB+ recommended
• Java：JDK 26 (build) / Java 21+ (runtime)
• Storage：~50 MB (including prebuilt DLL)

Environment Variables (Debug)

Known Limitations

• Windows only (D3D12 platform restriction)
• Async rendering Java layer still in development (C++ infrastructure complete)
• No external contributions accepted at this time (in-development project)
