Ryzen 3900x

[Jarhead]

Now i have intel i5-6600k, play with 10 or so most essential mods and maybe around 120ish assets.
Whenever my city reaches around 70k population, the speed slows down a lot.
Would upgrading to Ryzen 3900x solves this problem? I dont care so much about the FPS; it's the speed I care about.
Thank you!!!

Yes and no.

The issue with FPS dropping in lategame is largely due to the engine and how the game uses cores. You might see a 20-30% improvement going from something as "old" as a 6600K though, and the upcoming Patch should also help a fair bit.

Edit: However you might see the exact same improvement in this particular game with a much smaller, current generation CPU. Such as a 3600 or a 9700K. The 3900X is frankly overkill for games, and only precious few games are designed in such a way that allows them to offload enough work spread evenly across so many cores.

What he said.

[Jarhead]

So youre saying a jump from 4 cores to 12 cores will not show any significant improvement? And this game is not about "biggest and baddest" cpu?

That applies to almost every game on the market, yes. Faster cores, not more cores.

70k is rather small to be causing that much of an issue. Maybe you are using a lot of workshop? They are add=ons to the game and may affect performance from a little to a lot.

Is your CPU running at 100% all of time?

Time rates for all speed modes:
x1 speed = 10 seconds
x2 speed = 6 seconds
x3 speed = 3 seconds

The game can use up to 8 cpu threads. Your old i5 can only process 4 threads. It you upgraded that CPU to an i7 6700k, then you'd have 4-core/8-threads and max out the game.

Too much traffic is what causes slow downs. Early cities is caused from Industry supply and trying to meet commerce demand. This is a mistake, and you should be building more offices as they don't need freight and gets vehicles off the road.

It also helps to keep workers (residential) within 12-blocks (1km) of work, as your citizens will walk to work and not use a vehicle.

The vehicle limits are the lowest in the game at 16k. So it is very easy to hit it early and cause slow downs once reached.

It may be more wise to upgrade to Ryzen, but will cost more to upgrade as you need CPU, memory, and motherboard. But the 3900x is overkill as it has 12-cores/24-threads and it will takes some time for technology in games to catch up. I'd recommend minimum 6-core/12-thread CPU and the faster speed possible, as it will give you a minimum of an extra 2-cores/4-thread for other tasks than the game, plus keep your CPU from running 100% at all times and run cooler. But there is no real downside going for the 3900x it just may takes years for it to become fully utilized.

CPU and Motherboard* The RAM can be re-used just fine.

i will say on my laptop with a 7700hq i had same issues i currently own a ryzen 2700 and it has made a massive difference however on one note this game wont use over 50% of this processor in total so 3900x is massive overkill but if you can afford it why not get one if your more on a budget go to ether go to something like 2600(x) 2700(x) 3600(x) x being optional if you wish

You are correct. The 4000 series was the last DDR3 requirements for Intel,

That''ll be easier on the wallet and more affordable to upgrade to Ryzen for the extra cores.

Also, the 4th gen Ryzen should be release not too long from now. A few months or so according to the internet predictions, in case you need to wait and save a little more money.

My 3x speed is only 10-20% faster than my 1x speed. Traffic is always between 70-80%. Bunch of busses and metros, but nothing is excessive.
I would love to have that 3sec ex speed you mentioned, which I got in the early game. But it slows down along with the population growth.
I have industries, parklife, mass transit and after dark DLC. And like I mentioned earlier, I have around 10ish mods (the essential ones like TMPE and so on) and less than 150 assets.

[MarkJohnson]

Mods and assets don't typically mess with day speed, but I guess TMPE could as it manipulates the vehicles.

Maybe install the watch it! mod as it has a city limits button to show your vehicle (16k) and citizen 64k) limits.

Not sure what 10-20% difference is speed would be, maybe bring up the built-in windows stopwatch app and time it.

Maybe test with TMPE unsubcribed. Then resubscribe when done.

The 3900x is so overkill for this game that it's not even funny. Just grab a 3600 if you really need a performance bump.

It's called future proofing for 2030, when devs start pulling their finger out to utilise more cores.

I get that you're joking - But for sake of argument. Once that happens, we'll have i5's and Ryzen 5 equivalents with just as many cores.

Indeed.

[jhughes]

The difference between a 3900x and a 3600x for gaming is not really relevant. In reality, a 3600x (or even a 3600 and a better cooler) will give you 6 cores / 12 threads and it runs at almost exactly the same speed on all cores as the 3900x (which has 12 cores and 24 threads).

If you are doing things like rendering videos, streaming on line and playing the game at the same time, massive spreadsheets or databases, etc, Basically, gaming and doing lots of professional workstation things, then 12 cores vs 6 cores will matter. For gaming, it does not.

But a new Ryzen 3000 processor will certainly help .. with 32 GB of 3600mhz xmp RAM. if you get a decent x570 motherboard, you could later get a bigger (even next generation) ryzen processor .. but i doubt that will be needed for several game cycles.

3rd gen (or second gen if you prefer 1, 1+, and 2 vs 1, 2, 3) Ryzen processor performance is absolutely based on maintaining temperature as low as possible .. certainly below 70C when running these games. You WILL need a better cooling solution than comes with the processor to make that happen. I would say at the very minimum,a Cooler Master Hyper 212 or Deepcool Gammax 400 type cooler. The ryzen processors use precision boost, the cooler it runs, the higher it boosts in use. The better the cooler, the better the performance.

You also need a good video card for this game. Anything less than an NVIDIA 1060 (or probably an Radeon 580) should likely be replaced as well if you really want performance.

I have a ryzen 3600x, 32 GB of 3600mhz RAM, a samsung 970 evo 1TB nvme, and an NVIDIA 1080 GTX. It is liquid cooled (GPU and CPU) with an EKWB A360G cooler. I get about 40 FPS without the Dynamic Resolution mod and about 25 FPS with it set to 200%. Graphics card utilization is about 50% with no Dynamic Resolution mod and 100% utilization with Dynamic Resolution at 200%. My current city uses about 400 mods/assets and is a bit more than 16GB on loading.
