For legacy versions of Minecraft

In short, this mod absolutely beats the hell out of openGL and replaces it with Vulkan.

Very very WIP, this mod is replacing Minecraft main renderer so its very experimental, also this mod will have a LOT of incompatibilities, but i will try to make the mod as compatible as i can,

Is Minecraft fully rendered by Vulkan?

Not yet. When takeover succeeds, these stages are native Vulkan:

• Vulkan instance, physical device and logical device,
• GPU command buffers and synchronization,
• Win32 Vulkan surface and child-window swapchain,
• persistent staging buffers and upload images,
• final image copy/blit and vkQueuePresentKHR,
• optional experimental terrain vertex pipeline.

The main scene is still produced by LWJGL 2/OpenGL before being transferred to Vulkan. Block textures/lightmap, entities, particles, weather and GUI therefore remain compatibility-rendered. The default terrain preview is disabled because it is diagnostic, untextured and slower than the compatibility path.

Installation

Remove every older VulkanMod Legacy/Vulcanizator JAR and place only:

Vulcanizator-1.12.2-0.1.0-alpha1.jar

The new config directory is config/vulcanizator. An existing config/vulkanmod-legacy/renderer.properties is migrated automatically once.

Expected activation log

[Vulcanizator] Vulkan presenter is waiting for a visible Minecraft client area; temporary OpenGL bootstrap remains active
[Vulcanizator] Minecraft window became visible; Vulkan takeover is starting after ... bootstrap retries
[Vulcanizator] MAIN WINDOW VULKAN OVERLAY ACTIVE at 1920x1080
[Vulcanizator] Final frames are displayed by vkQueuePresentKHR; LWJGL 2 remains the compatibility scene producer
