Developing PC, PET and CA (old) for training product developers, I noticed that there is no visible difference between a 1 hour and 2 hour render under these circumstances - MR 5.1.1.33, three transparent plastic MXMs with measured IOR, 1920 x 1080 px, CPU i7-9750H 2.6 GHz, left 1 hour, SL 14.43, right 2 hours SL 16.31. I deliberately used a typical laptop in use in design studios. Image enlarged 200%. Two hours for such low resolution is the acceptable maximum. Of course Topaz DeNoise always does the trick, but doubling the render time with no change appears rather peculiar to me.
