Just FYI:
Anti-aliasing still doesn’t work in DX11. The last version I’ve checked was WINE 3.5. In WINE 3.0 does one get a fully black screen after the character selection. With Wine 3.5 does one at least get to see the UI, but the actual 3D graphics are still being rendered completely black.
So for now do I stay with DX9. It’s also a lot faster than DX11 and I can run two clients with AA enabled and both at 60 fps. I’m using a Nvidia GTX 960 with the proprietary driver.
