Again it is stunning to see the comparison with bicubic resize, haven't seen it for a while ;)
Your latest test 122645 has even more detail but also more noise, and take a look at the gun's "sights" - the bead - it gets a bit deformed. This has happened in other results aswell, but here it is stronger. I would like to see other frames of MagicUpSR3 refined + GrainPlate, could you please post more maybe?
