"Compile shaders before starts" only works under asynchronous shader option

[Linacanin]

Sorry if this was already discussed before but the setting "Compile shaders before start" only works here if the asynchronous (ubershaders) shader compilation option is selected, in the default synchronous option the "before start" compilation is skipped and it is the same as being disabled.

Is this working properly? If it is, there is any kind of warning about this?

Thank you.

Using Vulkan and tested the options on both preview Gamecube, retail Gamecube and Wii versions of Resident Evil 4.
