MSFS 2024 - Support all new technology graphics - FSR3?

Just to anderstand you ride. The files in the picture are from the Fakenvapi at point 7 not from the OptiScaler package. Do I need the OptiScaler files like libxess, amd_fidelityfx_vk or amd_fidelityfx_dx12 or only the EnableSignatureOverride.reg?
