3570k @4.3, MSI 970 4GB, 8 gigs of RAM, Win10.
Playing on very high except:
Bokeh off
FXAA
Motion blur off
Vsync off (adaptive in nVidia control panel trend on)
Since I can't get MSI Afterburner's OSD to show up in this game for the life of mine (steam overlay is off, no other stuff like that running in the background, played around with viewport/framebuffer OSD and still nothing) I can't tell for sure, but it seems that the game is running very smoothly. 60 fps almost all the time, exceptions where I notice the drops are:
Gas station explosions viewed from up close (drops to around 45 for a sec or two)
Discovering a new city/base (slight hiccup)
A LOT of explosions going around. I'm talking about 3-4 exploding tanks at once.
Running the newest drivers.
It's possible that having Afterburner turned off makes me not notice frame drops, but I do not see any screen tearing at all except during the mentioned moments, so to me that's satisfactory, and I'm really sensitive to tearing.
I hope there is an nVidia or another guide in the works showing differences in the different settings, so that I know what to reduce next to get locked 60.
Some technical hiccups aside, I'm having a blast with this game.
If I get more serious frame drops I'll just set everything to max with some downsampling and lock to 30. I'm enjoying myself way too much to care about such minor (IMO) issues.
