I use Macmini with MacOS Ventura 13.3.1, while the Mac running MetalFX sample code, and choose Temporal Scaler, makeTemporalScaler return nil value, and print "The temporal scaler effect is not usable!". If i choose SpatialScaler, it is ok.
guard let temporalScaler = desc.makeTemporalScaler(device: device) else { print("The temporal scaler effect is not usable!") mfxScalingMode = .defaultScaling return }
