Don't know if this was mentioned before - no matter, I found something.
Edit: all maps, Insurgents/Security, online and local
When joining the action after the truck drive, going into settings and change the effects quality value from "high" (or medium, very high) to low - apply - changing back to the start value "high" - apply - and going back into the game then the graphics performance increases instantly - in my case - by 15 - 25% (it's map depending).
Typically the game starts at 45-50 fps at 99% graphics load, when making the changes as decribed above I'm at stable 60 fps as desired and approx. 80% load which gives enough head room for action loaded situations.
No other quality settings change has this effect.
Probably other interested players want to try this out to confirm or refute this finding. Maybe it's just my config.
Playing at 4k/60 fps.

The game is completely degraded now for me. Frametimes look again like a rainforrest comparable to beta status in August last year. Heavy stuttering caused by all kinds of action, sounds and animations. The frametimes were in good (but not perfect) shape before the Feb.-update. Unbelievable. Degradation from patch to patch.
Is it possible that nobody cares for 4GB graphics? (I'm on a GTX 980).
Probably I really should wipe this nonsense off my ssd… I'm sick of it. Nothing than technical problems, tweak orgys and an AI that doesn't serve the name. Nothing that I could and would recommend to others. It turns into a nuisance.
While I understand that the game has its issues, I feel that list of negatives isn't a good representation of the game. The game is in a functional and stable state to play enjoyably. The game will only continue to get better with time and continued updates.
Now I feel a little bit kidded. All the problems that I experience do exist just in my imagination? Cool...
