Very cool video from DigitalFoundry. I respect them a lot for their comparisons and this one was particularly interesting to me because of the “Switch like PC” they built. The comparison is far from perfect of course but it’s a nice approach. One thing to notice is that on the Switch, shader performance can be increased a lot by using FP16 instead of FP32 for calculations (Half vs Float -> 16bit floats vs 32bit floats) because the shader cores of the Tegra can either process one 32bit shader operation or 2 16bit shader operations at the same time. You lose precision but this precision isn’t even important most of the time (except for something like shadows which you don’t want to look distorted because of lower precision). That’s something especially the NVidia cards on PC can’t do. They would just process one 16bit shader per 32bit core. Current AMD cards are able to make use of that though as well as the PS4 Pro and I guess this is one of the “secrets” of bringing a game like DOOM to the Switch.
