Hello! I had this problem with Stellaris since upgrading my PC around patch 2.6. Key note is upgrading my processor to Ryzen 5 3600.
Issue is mainly about camera choppiness/stuttering and it got better or worse with different patches along the road.
This stuttering starts from the beginning of a new playthrough but it's very subtle. Game is blazing fast early on and gradually slows down each year while the stutters are more frequent and noticeable. Around 2340-2350 game becomes unplayable for me - every few ingame days Stellaris is freezing for ~2-3 seconds.
I have also noticed that my CPU is running at 100% on one thread which is identical to the issue described in this thread "Camera Choppyness and Stutter in 2.6.1".
However applying this "fix" with cpu affinity didn't improve my gameplay at all, there is only a change in thread workload. CPU6 goes down from 100% to 60% after disabling and re-enabling.
Stellaris is running on SSD, Windows 10 v. 20H2 with a few minor backgroud processes (f.lux, msi dragon center, discord). Steam overlay is disabled.
Don't get me wrong, I expect late-game lag and/or slowdown especially when playing modded game but I don't think it should look like that. I remember from before 2.6 when I have played heavily modded games they just slowed down to a crawl (game often needed 60 seconds to pass a month). However there was little to no stuttering as opposed to now.
Right now Stellaris is much faster in mid-game and late-game, in fact I have measured time needed for a month to pass on 2.8.1 in 2354 - it took only 15 seconds on average! Full year took around 3 minutes so that's an awesome result. Unfortunately those freezes are keeping me from finishing saves.
I have uploaded a video showing this problem and a few screenshots. Also DXDIAG and game logs.
It was recorded on modded save (~40 mods, around 3/4 of them is music or graphical). IIRC this problem persists on vanilla gameplay, although much later around endgame basically.
I will be thankful for any help regarding this issue!
