Which is a shame because it would be glorious at 144fps :)
Hm yes I knew it was CPU-bound but even on a 5820k? Wow.
Then I guess I'd have moderate changes even with a Zen when it arrives.
Graphics settings don't change much to me, either. I hope for another performance patch - I really get that simulating every person is consuming, but somehow other games like Cities: Skylines manages complex simulations just fine. And this is the devs' second attempt. Either way, thanks again!
By default, I believe there is no limit. However much can get put into reserved RAM and virtual memory space.
My experiments in the game tell me that the factors affecting performance include vehicles, agents, pathing with signals and waterways, and laneways. This is especially true if you have more than 4 platforms (aka: terminals) at a station, as may likely be the case for passenger boats and railway stations.
i7 6700k OC'ed to 4.5ghz and a watercooled 1080gtx OC'ed to 2138mhz with cpu usage peaking at 31% and gpu peaking at 51%

I have a i7 4790K processor @ 4.0 GHz and a GTX 970 SSC, and try to avoid the causes in the experiments mentioned above, but the FPS does drop down to the low 30s and mid 20's in some situations on my end.
It makes a good challenge to keep in line with the game mechanics and
to avoid the "late game slideshow" effect.
What I find interesting is how even when the game is paused, FPS does not go up. Then it indicates a graphics card is a limiting factor too, and I wonder if they programmed LOD better it would increase FPS... I mean lower poly models kicking in closer to the player. Or, what if there was a "Planning" view mode where you wouldn't see models of houses, but their placeholders in certain colors, e.g. in Cities: Skylines where you use different layers for planning something. I wouldn't mind that look, e.g. there are games that work like that by default such as Mini Metro, Hitman: GO, etc, albeit not full-on games but still when there is a performance hit like this, there must be a workaround. I wouldn't mind giving up on realism if it meant 2x the performance.
It isn't the graphics card that is the limiting factor. I've run some test and checked the CPU and GPU load. The CPU and GPU runs in idling state (30% at most for both).
I concluded the fault is the OpenGL API renderer. The problem with the game is it only uses 2 cores. 1 core for the OpenGL and simulation, 2nd core for the algorithm for the agents and town development. If a person pause the game and the fps goes up, it is a clear indication the game simulation was bogging up the CPU, but this is not the case.
If you want to push up frames, you need to get a very strong single core CPU with an extremely high single threading score.
It's quite unbelievable though that a game in 2016 that relies so heavily on CPU power isn't developed for more threads. I guess we can't expect a fix for that either as it woudl involve re-designing the whole engine. What then, a 3rd game? Resulting in a game that runs as Train Fever should have.

Shame on you!
That's strange because I run an i7-5820K OC'd to 3.8Ghz with a GTX 970 and I've never seen my frame rate drop lower than 38 even in the most busy of cities.
How much and what type of RAM do you have? I've got 16GB of DDR4 which may be one difference (faster than typical DDR3 used in most PC's). TpF is a 64b program so it should theoreticly put everything it can into memory thus the more RAM the better.
I also use a program called Process Lasso which works to prioritize and balance core loads - when I was playing microsoft's flight sim FSX (32b program) just adding process lasso got me an extra 5 to 10FPS out of it and there isn't a more CPU bound game out there than that one IMO.
Edited to ADD: the above describes my performance without any of the little tracking boxes one can open. I've found that just 1 or 2 will only drop FPS by a bit but having 4 or more open can cause a real hit especially when you get up to 7 or more which if opened while viewing a large city with lots of traffic can do a number on FPS and easily drag it into the low 20's and occassionally even down into the high teens.
