I play in standard graphics, not HD, with everything turned down.
SD doesn't look thaaaat worse than HD when everything is turned down, but it makes huge difference in performance compared to HD. Propably it has to do with gpu memory and textures size requirements, but optically they are okish.
HD goes miles ahead when you turn on the other graphic settings, but when everything is low (i mean EVERYTHING) its also crap.
Its funny how much "cleaner" the battle looks, less distractions, you focus mostly to what matters.
I get 50-60fps on avg, maybe even 70 at some points, or even like 30s when i look through a lot of bushes. But game is certainly playable. Ohh, the monitor is 1440p. I used to play almost maxed out, HD client, at 120-130fps. I wll get a new GPU hopefully in the new year.
I just thought i should share it with you.
