I'm using 1070, 5600x, 16gb ram on a 4k monitor. Scale down to 50%, medium setting, DLSS off (Obviously), high texture setting, and my FPS ain't bad at all. This one runs quite smoothly so I suggest y'all who havelow spec to dial thosesetting down especially the resolution scale.
My suggestion is to add mouse sensitivity to the game, and that'd be it really. I was thinking maybe a crosshair so I know where I am looking at, but that is probably a low priority feature since there's nothing to interact with yet.
All in all, pretty neat tech demo.
