Vulkanized

This modpack is very light, replaces the standard renderer with Vulkan (Vulkanmod), squeezing every bit of power out of your GPU and boosting baseline performance:

Vulkan Pipeline: The core of the pack replaces the aging OpenGL (more than 30 years old) engine with the Vulkan API (thanks to Vulkanmod). This transition allows for software operating with very little abstraction between the code and the physical hardware.

Driver Overhead Reduction: By issuing direct hardware commands, this minimize the CPU bottleneck that typically plagues Minecraft.

Asynchronous Shader Handling: Leverages native Vulkan state management to eliminate stuttering during pipeline state changes and shader loading.

Vulkanized is optimized specifically for Java 21. It utilizes the Generational Z Garbage Collector (ZGC), one of the most advanced memory management tool in the Java ecosystem, less lag spikes in other words (be aware that zgc is going to use all of the amount of ram you put in the instance).

Sub-Millisecond Pauses: All garbage collection tasks are performed concurrently. This keeps stop-the-world pauses consistently below 1ms, virtually eliminating "GC spikes" or memory-related micro-stutter.

Physical Heap Allocation: Using the AlwaysPreTouch flag, the JVM claims and zeros out the entire 4GB of allocated RAM at startup (you can change it to more o less in the jvm arguments before initiating the game). This prevents the OS from dynamically reallocating memory pages during gameplay, ensuring a consistent memory floor.

Even in single-player, Minecraft runs an internal server. Vulkanized integrates ServerCore to optimize the game's tick-rate and entity processing.

Dynamic Tick Management: ServerCore stabilizes the MSPT (Milliseconds Per Tick), ensuring that world logic and AI never bottleneck the high-frame-rate output of the Vulkan frontend.

Multithreaded Geometry: Coupled with C2ME, world generation and chunk loading are offloaded to secondary CPU cores, allowing for seamless high-speed exploration.

Telemetry Suppression: Disables background performance tracking to free up disk I/O and CPU cycles for game-critical tasks.

Lithium Integration, is a general-purpose optimization mod for Minecraft which works to improve a number of systems game physics, mob AI, block ticking, etc.

Minimum of ram for this modpack is 1gb.

REQUIRED: A Vulkan-compatible GPU (Vulkan 1.2) and up-to-date drivers. Vulkanized replaces OpenGL with vulkanmod entirely; without Vulkan support, the game will not launch.

Recommended Java Arguments: Copy this and paste in the laucher instance in options selection java/memory and launch (this is optional) with 4gb of ram:

-Xmx4G -Xms4G -XX:+UseZGC -XX:+ZGenerational -XX:+UnlockExperimentalVMOptions -XX:+AlwaysPreTouch -XX:+ParallelRefProcEnabled -XX:+DisableExplicitGC -XX:+PerfDisableSharedMem

No Shaders compatibility, Since it doesn't work with Sodium and Iris.

Full cliente Side will work on single and vanilla multiplayer servers!
