Quick Question. What version of DX is Classic using? DX11?

Q: Will we see DX12 in Classic and the multi-threaded utilization enhancements at some point? If not, is there a technical limitation?

A: We are not planning to bring DX12 and the multithreaded enhancements to the Classic client. The multithreaded support greatly improves performance in large scale environments like Suramar or Boralus. Classic’s world and models are much simpler. It would also increase the system requirements.

Given that response, I assume DX11, yes.
