Same here. For Android is 5.4.3 cannot be usable at all.

It’s a known issue of Vulkan debug marker and we have disabled it temporally in 5.4.4, please wait for the patch or you could find the fix at https://github.com/EpicGames/UnrealEngine/commit/857f7740b9845181a713b7043ae4bc7b3915a34c

This fix doesn’t work on my end.
I needed to take back the fix for issue “UE-216306” (https://github.com/EpicGames/UnrealEngine/commit/8580bf1a6d07a5dcac3829aee43c392cbeffd0e9) .

After deleting the lines at UE 5.5.0 (ue5-main) > “Engine/Source/Runtime/VulkanRHI/Private/VulkanLayers.cpp” 402-405 which are:

bool bVulkanEnableDrawMarkers = VULKAN_ENABLE_DRAW_MARKERS;
	const bool bForceDebugUtils = bVulkanEnableDrawMarkers || FParse::Param(FCommandLine::Get(), TEXT("vulkandebugutils"));
	if ((bUseVulkanValidation || bForceDebugUtils) && (ActiveDebugLayerExtension == FVulkanDynamicRHI::EActiveDebugLayerExtension::None))

Then the performance comes back.

I fixed this issue by switching from “Development” to “Shipping” when package the game for mobile, it works fine without issues and FPS become normal again.
