Without SpatialUpscaling and set RenderScale to 1 in Unity, the GPU cost is around 14ms. With SpatialUpscaling and set RenderScale to 0.8 or 0.5 in Unity, the GPU cost is around 26ms. The quality with SpatialUpscaling is more blurred than Native. Is SpatialUpsaling usable and stable in iPhone 13 with iOS Beta 7?

Change to Macmini with M1 chip, the TemporalScaler is usable.
