@Felthry minecraft (at least on java) is kinda jury-rigged to just about work. im assuming it has no real API for rendering past opengl, so what it can really do is super limited. past that surface level explanation, i wouldnt know
@Felthry to add, theres no real imperative to adapt the java ver to dx11/12 because microsoft's focused on their cross-platform build of the game, and that'd just end up reducing the amount of win10 installs lmfao
