You already have NVIDIA Reflex and boost and AMD FSR, so you might as well add DLSS as well. (I personally prefer DLSS, especially DLSS 3 if possible)
As for HDR10, I think Diablo 4 already has it, but HDR is more than just extreme lighting it also adds more colors than the traditional 8 bit color, which may or may not improve the art style for this game. I mean, who doesn’t want more colors to work with? Especially since the art team had been carrying this game for a long time.
Not to mention, we can’t be left behind Diablo 4, what do you think?
