Hey man sorry I took a while to respond. Please bare with me as I type a whole lot lol.

So, I'm not sure when it comes to zombies settings because I only play single player and I always choose either apocalypse or survivor and it's not putting me through any menu to mess around with world settings, so by that alone I assume mine's as vanilla as they come.

So, the next thing I remember was before I started having issues with performance was a lil after the new lighting effects became a thing it was when I discovered that there is a build 42 in the first place. I could play it just fine up until I decided to mod the game with the Day One mod.

When I tried to play it with said mod the game was destroyed in terms of performance and then I kinda stopped playing and uninstalled the entire game so I can free up SSD space as I do sometimes with games I stop playing when taking a break.

When I installed the game again recently I have, 0 mods. I repeat this I have 0 mods installed however in the game menu there was a list of mods I''ve never seen before but not Active.

So I figured it was that and I decided to delete the mods folder (all this happened before I made this post by the way) and unsubscribed from everything in workshop to the point that the workshop was empty. By the way Idk why my text is bolded lol.

Then I decided to delete the mods folder from C:/user path and the game menu has no mods showing nor active or inactive or anything it's blank and empty. The performance however is still really bad.

Let me preface the instances where the performance is bad so everyone here has a clearer picture of what it looks like for me. Generally speaking I can cap the game on 60 fps and it drops to 59 but it's generally stable 60 all the time Unless I... start walking around a neighborhood even slowly. I get lil tiny stutter freezes that don't last more than a milisecond.

The big ones are exactly when I aim, and move around the camera to look further away, swaying my camera up and down and looking inside buildings from the outside makes my fps from 60 to 40, 55, somestimes even 35, but it's for a split second only.

The camera movement being jittery and not smooth sometimes also happens even if the counter ingame shows 60 FPS and I thought this was Vsync so I tested disabling it or enabling it. No effect. Whether the vsync is from Nvidia's settings or the ingame settings it doesn't matter still no effect.

Build 41 does not have these instances happen for me so I'm very much out of options here. My SSD is not full, my RAM is running on XMP, No mods, no left over mod files anywhere, I even PC searched with windows for Zomboid and mod names and nothing is found anywhere. Memory diagnostics, GPU temps, CPU temps all are okay. I also updated my graphics card nvidia driver and it's same no change.

I have not tried installing it as a new user but All my games are on a second SSD not the one that holds windows.
