i have a hd 6950 2gb too, and i get locked 30 fps but that only so far, it hasnt dropped yet but i got a feeling it will, make sure you have godrays switched off, you have to do it in the pref.ini, the volumetriclighting settings
can i ask what the exact area is ? id like to go there and see how it runs on my gpu, ive found that in all next gen games i get pretty much the same performence as consoles most the time slightly better unless a ubisoft game, im playing at 1360x768 too, so dont know wether that helps. its my tv native resolution anyway
my card is unlocked shaders and overclocked to 900mhz core and 1300mhz mem wich im hoping will help me keep 30 fps, playing on high settings with godrays disabled, shadows quality medium and everything else pretty much high, using a 2400 i5 sandybridge at 3.8ghz on all cores, my pc is on par with a Xbox One for sure
what are console gpu equivelents ? its a hd 7850 isnt it ? i know that a hd 6950 isnt much worse than ps4 or Xbox One gpu even if they are old, specaily when overclocked and performs better than a hd6970
what i usualy do is go on digital foundry and they usualy tell you what the console graphic settings are set to, then i match that, usualy works but if it drops on console then i sualy get the same drops too, but consoles cannot disable godrays.
im only at the part you get power armor but ive heard people say its smooth through there
