When rendering with forward rendering, the ComposeSeparateTranslucency call is called even when separate translucency is not enabled. Additionally, Downsample.HalfResolutionSceenColor gets called even though its results are not needed for the following passes.
Use the desktop forward rendering path, and run with the separate pass disabled.
