Here you go:
I also noticed that the traffic sliders seem to have enough of an effect on overall CPU load/performance that just by lowering them, you should be able to leave real-time traffic, online player traffic, and photogrammetry enabled.
On my system, PG on, real-time traffic, and all players visible works great with the rest of the traffic sliders at 15.
If you have decent internet, then just lowering traffic sliders and verifying mainthread latency should be all you need to smooth it out, in addition to taking the steps to set GPU and LOD settings previously discussed, of course.
You should only see improvement from messing with PG and streamed-in traffic if your internet service or the game servers are sh!tting the bed.
