ThreadTweak vs VulkanMod

ThreadTweak has no write-up on Specifiction yet; its figures are above.

VulkanMod is a free Minecraft client mod that replaces the default OpenGL renderer with a Vulkan-based engine intended to improve performance. Its listed optimizations cover terrain rendering, chunk building and entities, alongside reduced CPU and GPU overhead. It also supports native Wayland on Linux and windowed fullscreen mode. Installation requires Fabric, followed by placing VulkanMod.jar in the .minecraft/mods folder, and a GPU with at least Vulkan 1.2 support. The project lists Minecraft versions 1.21.3, 1.21.4, 1.21.5, 1.21.10 and 1.21.11. Shader support is not available, and there is no estimated release date; the README points users to Beryl for shaders. Mods that use OpenGL calls are unsupported, including Sodium, Iris Shaders, Create and Distant Horizons. Release 0.6.0 notes a terrain-rendering improvement when backface culling is enabled, an update checker, and fixes for alpha cutout sampling and a memory leak.
