Removing a bunch of mods, Primitive Survival being the most notable, fixed the issue immediately.

I am planning to move over to a dedicated server in a few days and see if that solves the issue, I havent considered that it could be an issue related to this at all until very recently.

Latter, the other player hosts the server locally on his computer.

It is a local server, we are about 10-14 hours into the playthrough and don't have many items, and only about 3 barely-chiseled blocks in our base, although the stutter has existed even before we *made* a chisel.

Tested separately in Singleplayer for 30 minutes, 10 with VSync at Fast, 20 with VSync at 'Off', also following everything else on that thread. Fullscreen optimizations disabled, graphics preset somewhere in between Medium-Low. There's the usual very minor stutters as you transition areas, which is not a problem and not all that noticeable. The noticeable drop to 1 FPS never occured withing this save. So this is either something related to lighting (doubt it, as we had like 2 torches and a campfire at most), or something related to Multiplayer (LAN play in our case), also perhaps noteworthy that my buddy didn't follow the steps on the Nvidia Fixes thread.

Indeed, that was the thread that I mentioned. I personally tried everything listed in that thread, but it did not seem to fix the issue.

My friend and I am playing on a locally hosted server, I have an Nvidia GTX 1650, 16 gigs of ram, an intel i7 11800h CPU and an SSD and he has an even better GPU than that (RTX 3050), but we both get the occasional microstutters that drop the game down to 1FPS or so for a fraction of a second before going back to normal. This has happened plenty of times for both of us to be noticeable, and is frankly quite annoying. I followed pretty much all the solutions described in the Nvidia fixes thread and the Wiki thread, but none of them seemed to fix it. I play on almost the lowest settings in hopes of fixing or remedying the stutters, no bloom, no shadows, no godrays, nothing fancy, FPS maximum at 58FPS set on the Nvidia panel, and all the normal, less FPS impacting stuff at the defaults of the medium preset. I got the friend to do that command to log any ticks that take above 40ms, and I'll provide the txt file with the post. I really hope to find a solution to this, as it is the single most annoying and noticeable problem that I have encountered in VS. client-main.txt
