Some information on the graphics settings.
Tessellation, textures, shadows, terrain, vegetation, water and ambient occlusion can't be switched without restarting the game.
AA isn't very demanding. 45,9 on high and 46,7 off.
MSAA is however, 32,5 with 4x and 46,7 off.
Mesh is not either. 46,7 with high and 45,2 with ultra.
I can recommend turning post-process quality to low to gain a significant fps boost. Sadly, I do like some of the features in that option, but I definitely don't need motion blur.
Geforce Experience recommends settings that give me 48,7 while the in-game "automatic" setting gives me 47 fps.
Make sure you play the game in windowed. I got 41,6 in that mode, 40,9 in fullscreen and 39,8 in windowed fullscreen.
HBAO isn't very demanding either from HBAO to HBAO Full. Only 43,0 to 45,8.
If you already have Textures on Ultra might as well choose Fade Touched. 0,4 difference in fps.
Nevermind, makes my game stutter insanely.
Tessellation gives 43 on medium and 40,7 on high. Will probably just stick with medium.
