Before setting my render hardware interface to Vulkan, I check if Vulkan is supported: ```auto FModuleManager::LoadModuleChecked(TEXT("VulkanRHI")).IsSupported() ``` Then I confirm Vulkan is the used RHI: ```auto # Engine.ini [/Script/WindowsTargetPlatform.WindowsTargetSettings] DefaultGraphicsRHI=DefaultGraphicsRHI_Vulkan ``` Next I start my project in PIE and I assert because one of the methods I call finds not a single supported screen resolution while using Vulkan: ```auto verify(GDynamicRHI->RHIGetAvailableResolutions(ResolutionsArray, true)) ``` I use a GXT 1070TI with the latest drivers. Are the above methods simply fragile? I can’t risk having an X amount of devices asserting because no resolutions are detected. \*Edit DX11 and DX12 work absolutely fine and return all resolutions. I am going to assume this is a bug on UE’s part, anyone can confirm? Since setting an RHI requires a full app restart and testing for available resolutions requires the RHI to be loaded… This is breaking. ---

Wait what, it’s not been implemented? ```auto void FVulkanDynamicRHI::RHIGetSupportedResolution( uint32 &Width, uint32 &Height ) { } bool FVulkanDynamicRHI::RHIGetAvailableResolutions(FScreenResolutionArray& Resolutions, bool bIgnoreRefreshRate) { return false; } ``` Bit late for Aprils fools guys! > [Can't change resolution using Vulkan ??](https://forums.unrealengine.com/t/cant-change-resolution-using-vulkan/480528) > [When will VulkanRHI be updated to return screen resolutions?](https://forums.unrealengine.com/t/when-will-vulkanrhi-be-updated-to-return-screen-resolutions/454976) ---

heya, did you find a solution? ---

It’s not implemented in engine code, no solution ---

This is kind of ridiculous, are there really no workarounds in C++? I have yet to find any way to do this while using vulkan ---

No, they like not implementing and breaking things. ---

> [@Roy\_Wierer.Seda145](#): > > `RHIGetAvailableResolutions` Not on 5.2. I’m still locking to the one resolution reported by GameUserSettings on Vulkan which is pathetic. ```auto FS_SupportedScreenResolutions SupportedScreenResolutions; if (GetCurrentRenderHardwareInterface() == E_RHIMode::RHI_VULKAN) { // Vulkan for whatever reason does not implement RHIGetAvailableResolutions, making it an odd one. // https://forums.unrealengine.com/t/ue5-1-1-supported-vulkan-rhi-returns-no-supported-screen-resolutions/873006 SupportedScreenResolutions.Resolutions.Add(GameUserSettings->GetScreenResolution()); SupportedScreenResolutions.CurrentResolutionIndex = 0; } ``` ---

I’ve made a plugin that generates resolutions based on the monitor’s aspect ratio. It’s not perfect, but it’s better than nothing You can download it from [Github](https://github.com/jangomango2001/UE4-VulkanResolutionHelper) or [Itch](https://jangomango2001.itch.io/vulkanresolutiontoolkit) ![screenshot-2024-08-21-025125-asus3eq6](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/8/2/b8224297404425b67a7cd768cf15463b1cd324d7.png) ---

Confirmed this is not implemented in 5.3.2 either. Is this implemented in later versions?
