Hello, when i change the graphics renderer from dx12 to Vulkan i can’t change my game resolution, because the resolution box is now completely empty

Using Directx 12

I run Linux (so I must use Vulkan), and the Get Supported Fullscreen Resolutions function returns nothing.

I dug through the source code and found this:

bool FVulkanDynamicRHI::RHIGetAvailableResolutions(FScreenResolutionArray& Resolutions, bool bIgnoreRefreshRate) { return false; }

I could be wrong, but that looks like it makes it impossible to get the resolutions when using Vulkan.

Verdict: Yes, with Vulkan you cannot get the list of resolutions via GetSupportedFullscreenResolutions

However, there might be a different way to get the resolutions. (Like a plugin or something)

Hope This Helps
