Hello everyone,
I had the same issue however; I found a solution after searching in google found this:
Release Version 0.30 - Froglet 
· Joshua-Ashton/d9vk · GitHub
1- There is file called "d9vk-0.30.tar" download it
2- Extract the file (I'm using 7-zip to extract the file) and you will get d9vk-0.30 folder
3- Inside folder there is "d9vk-0.30.tar" extract it again
4- Go to the extracted folder "d9vk-0.30" then go x64 file, you will see 6 files .dll which is all directx versions AND VULKAN!
5- Copy all 6 files and go to the to the lost ark game folder should be like this by default: C:\GamesMailRu\LOSTARK\Binaries\Win64 (unless you put it into different path) then paste files there
and that's it open the game
in my case my fps was 60~80 with dx9 and annoying stuttering in game, after I put the files in game you will noticed that the game will use VULKAN instead of dx9 (you can see that by using msi afterburn) and I got 160 ~ 200 fps and the stuttering issue is gone, I'm surprised that the game support vulkan and its amazing.
I highly recommend to use radeon image Sharpening in radeon software to get better graphics in game, it make the game looks way better and more beauty (you can increase or decrease the image sharpening if you are using Radeon™ Software Adrenalin 2020 Edition (I got 19.12.3 version).
I hope it solve this issue for everyone 
I noticed there is new version for d9vk in website but honestly didn't try it yet, you can try it and see how it goes, and there is 1 issue which when you quit the game, you will need to close it by using task manager, I don't know why the game doesn't close it self but doesn't matter as long as we can play the game.
There you go: Releases · megai2/d912pxy · GitHub
It will make the game that use directX 9 use directX 12 instead which it should improve performance and stability depends on your PC SPECS !
for the installation guide you can check out here: Installing · megai2/d912pxy Wiki · GitHub
I didn't try it in guild wars 2 but he already made it to support game called blade and soul which is the game I was playing it all the time.
in short answer, if this mod d912pxy wasn't exists, I would be pissed off and throw my red devil RX 5700 XT to the trash, because the game it stutter A LOT and low fps on using directX 9, I'm really happy that guy(megai2) who create this mod support blade and soul, even though the game POORLY OPTIMIZED because it only use ONE SINGLE CORE OF THE CPU!
The main problem of AMD GPU 5000 series is the old online games like (blade and soul, guild wars 2, lost ark....etc) that use directX 9 having drop FPS and stuttering, they really really need to fix it.
Hope it helps you in GW2
