I've just reached the Mother Base directly after the first level.
I'm running the game maxed out from my SSD with HBAO+ forced via Nvidia Inspector (in-game SSAO off). GPU is in factory OC mode running between 1392-1404MHz. To maintain a framerate of 60 fps or above at all times (even during cutscenes with heavy DoF or particle effects), the maximum I can push the DSR is 1440p (native 1080p display), with GPU usage anywhere between 45-95%.
(2880x)1620p DSR (otherwise known as 2x or sometimes as 1.50x super-sampling) I was getting a 60 fps lock, but once the heavier particle effects would kick in, it would drop into the sub 40s (especially during the intro area). At 4k DSR, I was getting an average of 44 fps in the first level while free-roaming.
RAM/VRAM usage is very low, at only about 3.5GB/2.5GB respectively. My CPU doesn't seem to be terribly tasked in this game either; it's barely pushing 20% usage so far. One thing I'd like to do is disable in-game FXAA and force SMAA via SweetFX, but the game doesn't currently have an AA "off" option, and I can't get Reshade to work yet.
Minor quibbles though. The game is a "solid" step up from Ground Zeroes in about every area visually, and it's running great.
