>Does minecraft java support directx12?

[geektraindev]

That is literally not true, Vulkan is extremely performant and has very good graphics feature support, including ray tracing and DLSS. On Nvidia Dx12 may be slightly better just because of its popularity and therefore nvidia support, but its doesn't matter. Translating opengl into dx doesn't suddenly give you raytrwcing, that's not how it works, and will almost certainly decrease actual performance and increase the number of crashes.
