    I'll save everyone the time:

    You gain ~0.7 VMAF score (both above 90) and save 33% bandwidth at the cost of 3.2x longer encoding for (presumably) some set of 1080p clips used in testing.

      what about decoding speed?

      just how much worse will it be for my old CPU?

        Should be the same?

          I don't know that much about video codecs, could decoding performance improve, given the reduced input size?

            Doubt. Check your igpu or gpu should have dedicated hardware decoder for h264.
