Hello, only recently when I batch render in Arnold (GPU) Maya 2020.1 there is a very long period where it "// Result: Rendering Postprocessing" takes a very long time. The render would take 2 minutes but the Postprocessing takes 10-15 minutes. I have reinstalled the drivers and made a fresh scene but after say 2-3 frames the Postprocessing takes increasingly longer. I have no post processing effects. Any thoughts? GPU 2080ti x 2
