AMD Users

AMD cards perform better on OpenGL because Minecraft's new Vulkan engine is poorly optimized and contains code bugs that clash with AMD's hardware . Set the Defalut API to openGL

Nvidia Users

Nvidia cards perform better on Vulkan because their hardware handles Minecraft's unoptimized code much more efficiently.Set the Defalut API to Vulkan

I suggest you install a third party app.The benefits are that you can install mods and reasource packs more easily.
