Actually, it looks like OpenGL may not work for this game, since it utilizes more shader functionality than Feraline did. If you wouldn't mind doing some testing for me, please see if any of these options work. (Apparently it wasn't necessary to make a separate vulkan/opengl build.)
You'll need to run it through the terminal. I believe on Windows, this would be Shift+Right Click on the empty space in the folder where you have Wilden installed. Find "Open PowerShell Window Here" or "Open Command Prompt Here", something along those lines.
Then, try each of these commands in order. They will run the game with different rendering methods. After running one, see if the game crashes, doesn't open, opens with problems, or opens and works well, then run the next and repeat.
- ./Wilden.exe --rendering-driver vulkan
- ./Wilden.exe --rendering-driver d3d12
- ./Wilden.exe --rendering-driver opengl3
- ./Wilden.exe --rendering-driver opengl3_angle
My predictions are, the first one will crash instantly, the second one may or may not crash, the third will launch with graphical glitches, and the third one will never open.
If none of these work, unfortunately there won't be a way to make this game run on your system without using opengl3 and having graphics artifacts. If any of them do work, I will add a compatibility executable next to the main one.
