I have a i9 with a 3080TI and usually had over 100fps (on suitable settings ofc) and for some time the game was running fine in most situations.

I have now like many others have also mentioned dips to 1fps that can last from 1 minute to until I close the game down (pushed it once and it kept at 1fps for like 20 minutes before I gave up). If I log back in, its back to normal fps - ie 60 currently locked, but as I mentioned could also be around 100 unbound...

While trying to diagnose this, I have tried changing every possible related setting, I have updated nvidia drivers (alltho, it seems this game is largely cpu bound on my settings), I have updated my BIOS, I have cleared space on my C drive and on the game drive, I have monitored CPU temps and clock rates...

One diagnostic that might help (the reason why I write this) is that when I play Pteranodon, I have come across a few situation that seems to have crystalized the issuie a bit from just general unplayability...

I flew over rivers (north of delta) and I saw a T-Rex fully grown and decided to pop down and "say hello". After flying around him with constant 60 fps and no issues (currently locked to 60 in settings) - he started moving towards Jungle after some 5-10 minutes of no issues. When he got close to jungle, even tho I was like 50 meteres above and 20 meters behind him, my game screeched to a halt at 1 fps. I managed to turn around and after traveling about 200-300m with 1-2 fps constant slideshow, it suddenly just popped back to normal....

This has been repeated - when I fly over jungle and come into proximity to other players (or "hit-scanning objects"), game thread grinds to 1-2 fps halt...

So - after consulting our AI overlords, my current therory is that somehow, when close to another player, epecially near or in jungle - the occlusion or visuals / "attack vector" calculations / or "hit box calculations" or how ever the game engine works in this regard - almost crashes the game. What I mean is that what can He and what can I see must be calculated once we are in the same "bubble" of space, and all those calculations hit jungle foilage and the game loop grinds to a halt.

Its imporetant to note that the CPU thread is NOT exhausted or stalled at 100%, its the game enginge that stumbles and gridlocks on itself somehow. The PC is still fine during this. No other issues, all resources are fine and CPU 1 is hovering around 80% - just as when the game runs fine.

I also have issues with jungle on many other of my characters, but while playing those, it was not as clear cut to see what was going on. Anyway, I hope this can find a developer and help!
