PSA: Vulkan broke my project

So I was doing step by step what is in the video, and when I changed in Platforms - Windows → Targeted RHIs → Default RHI to Vulkan and Restarted the project as it asked, it was constantly crashing and I could get back into the project.

I had to go to the project folder/Config/DefaultEngine.ini find the DefaultGraphicsRHI and change it back to DefaultGraphicsRHI_DX12.

I don’t know if my PC is so problematic or if changing to Vulkan should be said with some caveats.

So this is just a manual for people who would encounter the same problem as I did.

Have you installed the libraries? You might find something here about it.

It might be a sign that you need to update your graphics card drivers.

There wasn’t any mention about installing some additional libraries if I’m not mistaken. Thank you for the link.

I have the newest drivers.

Researching this further, it seems like Vulkan doesn’t like having SM6 (ShaderModel 6) enabled as it’s not supported. But overall Vulkan isn’t brought up to speed with DX12 implementations maybe?

Gonna get Mike’s thoughts on this, might need a revision for that lecture.
