If you change the Group Privacy setting to local and turn Social Notification Frequency to off it really helps a lot.
Also, if you turn the Overall Quality setting to Very Low and then just tweak the individual settings to your liking you will gain some FPS and some of the stuttering will stop.
Camera/Weapon Blur: Off
Texture Streaming: High
Aniso. Filtering: x16
Mat. Complexity: Ultra
Draw Distance: High
Environmental Detail: High
Terrain Detail: High
Character Detail: Ultra
Ambient Occlusion: Medium
Volumetric Fog: Off <—huge fps boost
Screen Space Reflections: High
Me: Also high
I get between 80 - 150 ish FPS with these settings on an 8700k 4.6ghz and a 1080 FTW 2. Play around with the setting and see what happens.
DX12 in this game, for some reason, is still “beta” and barely works for most people. I personally lose about 20fps with the same settings as DX11 but that’s just me.
It just seems like the game isn’t pre-rendering frames. I see the same kind of stutter in games if I turn Low Latency Mode to off in nvidia control panel. It’s installed on an 970 Evo so I don’t know why loading anything would be a problem.
Hope this helps.
