Unreal Engine 5.4.4
Windows
Does anyone know how to reduce the delay before Unreal Engine 5.4 starts compiling Shaders? (Multiple minutes)
The process itself runs smoothly (it uses the limit I have set in the BaseEngine and uses nearly all of my Cores) but before the compilation starts there is a delay when Unreal tries to create in AppData in the UnrealShaderWorkingDir WorkerOutputOnly.out files these fail with the Results “Name not found” (I saw this through the Process Monitor) and then it suddenly works without problem.
The ShaderWorkers are already created and they wait until Unreal stopped trying to “edit” the files in the folder.
It does not happen in 5.3. I have uninstalled all Incredibuild Components and reinstalled Unreal and Visual Studio 2022 already.
I changed the Shader Cache location already but it still access this folder.
Short: There is always this delay where it makes these errors (only visible through the Process Monitor) and it does not use any of my CPU Cores and only writes/reads on my C Drive (AppData Folder mentioned above) at a low speed before starting the Shader Compilation which runs then normal.
