Does anyone know what the DLSS resolution upscales from if you're playing at 1080p?
Edit: More info, a friend is running the game at with resolution set to 1080p with DLSS on and since I'm unfamiliar with DLSS and how you configure it, I don't know if he's
a) running the game at 1080p, making it 'look better' with DLSS and outputting a 4k image then output to 1080p, kinda like DSR i suppose but without having to fiddle with the resolution setting
or
b) He's running the game at some resolution less than 1080p, using DLSS to upscale 1080p and outputting that image.
I assume it's the latter, especially because he's getting ~20 more frames with DLSS on than off.
