On a radeon 7770 with 1gb of memory and a i5-3330 and 8gb of memory.
On win 10, game installed on 7200tpm HDD.
D'ont have time to make a lot of test, but game run really smooth in low settings - only try the first area:
AVG at 47FPS - with the lowest settings - evrything disabled, lowest draw distance - in 1280*720.
AVG at 17FPS - with max settings - everything enabled, no frame limit, draw distance at 30 - in 1980*1080.
So depends on what you wish, but the game still really enjoyable even with the lowest settings.
Hope this could be helpfull.
