Hi, best to start here if you haven't seen it:

What are your system specs? And what resolution and detail setting?

The map / population size is likely a big part of it. Those are very large start sizes, wayyyy above vanilla.

Mods can def be an issue, some more than others. Many poorly optimized mods out there, vehicles especially, that chew up a lot of memory or have little/no LoD optimizations.

There's also a few misc mods that can hit FPS fairly hard or don't get along with each other (like Advanced Stats and Priority Signals).

Also since this game naturally trends into low FPS, check your Vsync settings, both in game and in video driver. In my case OFF in game and Adaptive or OFF in nvidia Control Panel made a big improvement.

I'll have a look at the vsync settings. But my system is a new one that I built this summer. Has an i9 (can't remember flavor off the top of my head), 64GB ram and a 4080 ti. I shouldn't be having performance issues... unless the game is poorly optimized.

Don't worry, this game will burn your puny system like all others before it 🔥

GPU and RAM will help, tho it's still a single-threaded process for CPU. Also I don't know how many other games try to simulate tens of thousands of unique entities all at once

Mods def aren't optimized (overall).

I wish they didn't simulate or path everything like they do. There's gotta be a way to have a compromise between trying to be realistic with regards to pathing and having a functional larger world. I mean Sim City has been doing large cities for a couple decades... surely this can't be that hard now.

For me, there's only really a couple challenges for this game. One is the early start when vehicles suck and it's harder. The other is later game when money means little (in the map in question I'm making 1B a year and my industry is still only just getting ramped up) and you need to deal with traffic, convincing pax to use your transport and getting the volume of goods needed to the cities. Of the two challenges, I much prefer post 2000 to the early game.

I think the key diff is this game is simulating unique agents, each with specific origin and destination, whereas SimCity, TTD, etc most things are fungible and can be stuffed anywhere.

I agree there's probably another way, something that retains some of that unique agent aspect while meta-simulating other aspects on a broader level. But that'd be a major game engine change, so maybe in a future title...

Either way, I often see it mentioned that multi-thread would be a massive performance improvement even if everything else remained the same.

Have you tried Very Hard? Combined with some industry mods it's a stiff challenge. But it's also style-cramping if you just want to build cool stuff. Ofc can change it whenever wanted.

So far in the beta it seems like traffic has been massively improved (so much that it almost feels nerfed to me). So if anything the traffic and passenger challenge just got easier. But it *looks* way better!

Anyhow def look at those performance suggestions, because I feel like you should be getting better performance even with the large cities/pop, but maybe someone else can comment. (I mean, I'm running a *second-gen* CPU lmao 🤣 with 400+ mods in 4K ultra and I'm getting your FPS range..., but only vanilla-sized cities and it's early 1900s.) Probably got a bit off-topic for Workshop discussion tho... maybe the main Discussion group would have more feedback. Cheers!

I'm hoping to have some time later this week when I'm back at home (on the road for work now).

Haven't tried very hard. Honestly, I enjoy the building aspect, rather than the challenge itself and will frequently play in sandbox mode just building things out. I've done a few games from 1850 (and it was a grind until I hit the 1930/40s). Now I rarely play before 1960, and frequently just start in 2000.

I think I've done maybe 1 hard game ever? I've only just gotten back into TF2 in the last 6 mths or so after taking a break for several years. And yeah, posted this in the wrong spot. Took me a while to even find it after the fact.

So removing the vsync made a noticeable difference. Still getting some FPS drop when I zoom around, but pretty steady in the 40+ range now.

Interesting! Very similar to what I had.

I tried setting vsync to Adaptive in nvidia control panel, which in theory should work better in low FPS situations. I found it similar to vsync off, maybe slightly lower FPS. Ofc with it off entirely I get some tearing when I have higher FPS, so I might turn it back on Adaptive for a while.

Either way, vsync enabled via the game settings menu was a dumpster fire for me.
