what about perf. shadows? and maybe FPS?
perf. shadows?? not sure what you're talking about there.
i run on a laptop bought in Jan 2015, exact specs i can post on request. Suffice it to say it's not the best of rigs, but gets the job done when it comes to most games.
FPS on max shaders without soft/whatever is about 5 for 50k bricks or something idrk
FPS on minimum/off with 200k bricks is about 28
low is playable until like 30k bricks, at which a noticable graphics delay starts to appear. no fps drops till it gets higher, though.
i generally just play on minimum and have no issues, and switch to shadows only for images. I can still move around to pose the shadows while they're running, but FPS is pretty bad so its not very playable.
