Metin2 - DirectX 11

[Kaiser 1238]

Hi, I've been working on Metin2 graphics and DirectX as a hobby for a long time. My priority has never been visual spectacle; my only goal has been to improve the infrastructure beyond DirectX 8/9, and after all the effort and work, I have finally fully upgraded to DirectX 11. I would like to point out that no APIs or wrappers are used. There is no actively used DX9 code in the project.
Of course, from this point on I will focus on the visual aspect and see what can be done with DirectX 11.
If there are no issues, the detailed changelog is here.
I am open to ideas and criticism.
