GPUBooster is a powerful optimization mod designed to significantly enhance the performance of your Minecraft gameplay by directly integrating with the game's render system. It addresses common performance bottlenecks by implementing advanced techniques such as Direct State Access (DSA) for various buffer types like VBO, EBO, and FBO, as well as textures. This reduces the number of operations required for rendering, leading to a smoother and more responsive gaming experience. The mod also introduces a pooling system for VBOs and EBOs, allowing for efficient reuse of these resources. By optimizing these core rendering components, GPUBooster aims to provide a noticeable increase in frame rates, making the game more enjoyable, especially for players with less powerful hardware or those who use demanding shader packs. The mod achieves its performance gains through several key mechanisms. It leverages DSA to minimize buffer binding operations, a common source of overhead in rendering pipelines. Furthermore, it implements a Renderbuffer Object (RBO) for depth, which can offer a slight performance improvement over traditional methods, especially when DSA is enabled for FBOs. For CPU-intensive computations, GPUBooster utilizes SIMD acceleration through the Vector API from the jdk.incubator module, speeding up processes like frustum culling and weather rendering. It also includes features like a "VAO Format" cache, UI text batching, and fast collections in loading systems, all contributing to a more efficient and faster overall game execution. These optimizations are crucial for maintaining high frame rates and reducing stuttering, particularly in complex game scenarios. GPUBooster is designed for broad compatibility within the Minecraft modding ecosystem. It functions seamlessly with popular client-side optimization mods such as Sodium, Embeddium, and Iris, and is also compatible with shader packs. The mod supports a range of Minecraft versions, including 1.21.7, 1.21.8, 1.21.9, 1.21.10, and 1.21.11, as well as Forge and NeoForge versions 26.1, 26.1.1, and 26.1.2, and Fabric and Quilt loaders. Importantly, GPUBooster is a client-side mod and is required on the client only; it is not supported on the server, as its functions are specifically related to local rendering performance. Players should ensure their GPU's OpenGL version is 4.5 or higher to access all available features, as older versions may limit functionality. Installing GPUBooster is straightforward for users of Fabric, Forge, NeoForge, or Quilt. Simply place the mod's JAR file into the `mods` folder within your Minecraft directory. Before launching the game, it is crucial to verify that the necessary JVM argument is correctly added to your launcher's configuration. Specifically, you must include `--add-modules jdk.incubator.vector` to enable the SIMD acceleration features. A detailed guide for popular launchers is available to assist with this setup. Additionally, before starting the game, it's advisable to check your GPU's OpenGL version to ensure it meets the 4.5 requirement for full feature availability. If you encounter issues, particularly crashes, double-checking these JVM arguments is the first troubleshooting step.
