don't really understand it, but it works..
Vulkan.
I have to delete dxvk config before launching the game, otherwise it crashes instantly.
the overall quality is better, the FPS is sometimes better, but with huge lag spikes.
DX12
it also works, but nothing seems to change.. maybe some more FPS (2-5)
idk whats wrong, but I can't get more than 20FPS in Dalaran.. with or without Vulkan or DX12..
it's not about my config, cuz R5 3600 and RX580 G1 Gaming is a bit overkill for WotLK maybe its the limitation of the game engine itself, and there is nothing you can do about it.
