How much vram does this game need?

[Too useful dispenser]

7.5k population with little to no details yet i only have 30 fps up close
Ultra settings 1080p, rtx 3060 ti (8gb vram) and 32bg ram
Why?

Depends on amount of asset heavy DLC and Mods... Especially if any mods or DLC broke with the new free update/Hotels & Retreats/3 creator packs.

So I have a custom size set for my page file of:
Initial Size (MB): 4982 (Basically 4GB of VRAM)
Maximum Size (MB): 32257 (Basically 32GB of VRAM)

I've found having a small initial size keeps the VRAM from staying full of junk, while still being able to use a lot of space... I also have my page file on a 7200RPM 500GB HDD, so I don't wear out my nice M.2 SSDs with VRAM read/writes.

And my build is Ryzen 5 3600, MSI Radeon RX6600 (not XT), 32GB VRAM, and probably medium to high graphics settings for 1080p.

I also have almost all of the DLC other than Airports/Hotels&Retreats/Disasters/most creator packs.

I don't have any mods enabled, and other than a bit of a stutter during the absurd initial load, I don't usually have any issues (the new release added some bugs unfortunately.)

ALL OF THEM.
8GB is roughly enough to fill 3000 asset if we don't count DLCs. But then again assets aren't created equal so take that as grain of bacteria.
Your performance issue is less likely due to VRAM tbh, unless you ran your game at 8K or something, or you planted insane amount of high poly trees, etc... There's only so much the PC can handle. When you went over the line, you went over the line.

this game consumes all 8gb of vram and i believe it also consumed 13-15 gb of ram last time, and my city is small..... what the ♥♥♥♥

The people responding are confusing vram, with ram. Vram isn't your problem. Your are running ultra settings on a 3060. It's hard to hold 60 fps with an 80 class card. At 32gb you have enough ram for 5 or 6k in assets. Your gpu's vram at 8gb is fine for this title, it doesn't depend on vram like that. I have 4gb of vram. It's just the game. Every open world simulation suffers this. Resource usage scales badly the bigger your world gets. That and this is an old very patched game, single threaded mostly, and soon to be replaced. The bottleneck is the game. you can check task manager, but I'm sure its fine. Look into some of the optimisation mods even if you want to play vanilla, they are worth it.

Well I guess that what happens if you add tons of dlc without initially preparing the game for that. The only game that cannot run above 30 fps considering its age, lol

Show me a sim that doesn't get slower with size. Or another game that's been maintained and added to for a decade that's hasn't had spec creep. I get it can be frustrating, but it's the nature of the genre. No Maintained software is immune to spec creep. Machines get more capable and devs figure out how use theose capabilities. Then at some point enough has changed it's time for a clean sheet. Cities is at that point now, so I don't know what else to tell you.

That's exactly what it should be. Everyone gets that.

If you want more FPS (unneeded in this ant farm game), then you can install mods to give you more fps,

This is a simulator, so it takes a lot of CPU time to run the game itself, plus the CPU has to process tons of GPU to pass to the video card so it can make a 3d world. This ends up choking out the CPU and delays data to the GPU, so FPS suffers from the GPU constantly waiting on GPU data to reach the GPU.

A.I. data can be very complex, on top of that, the game has to process 80,000 other agents, (equivalent to 80,000 other CPU controlled players in the game), so you can see it is very difficult to get high FPS when the game has to process so many other units in the game.

Imagine how slow you FPS games would run with 80,000 people attacking you at once. You wouldn't even get 1 FPS.

EDIT:

Here's a video of why the AI consumes so many resources and slows down the game.

If you means me, then you are confused. When i said 8gb vram = 3000 assets I REALLLY means 8gb vram = 3000 assets, tested on RX580 8GB gpu. I wasnt talking about system ram. All those texture needs placed to go ya'know.

Does it affect performance by tanking the vram? Yes, it does, thays why I tested it how far can I push my GPU. Especially on old platform with slow DDR3 system RAM. For people with new platform, the impact shouldn't be that bad.


You likely questioning what gpu have anything to do with system ram. When VRAM full, gpu will start sucking the far slower system ram...

That said, OP os providing not much info. His performance issue can really be anything. Game resolution (there are always people that crank Dynamic Resolution to 300% and complain why the game peform so bad) , how big is the city, asset count, quality of asset, game technical problems like stuck citizen and broken nodes, obsolete mods, etc.

It works for me with 7k assets with this configuration.
ryzen 5600g
32gb ram
and virtual memory 120gb
2 GB memory graphics card.

later I added 32 gb more of ram and removed the virtual one and it works very fast 23 fps

with all the dcl a minimum of 32gb ram is required

I have a 4gb rx580, 32gb of ram and more assets then you. That just isn't what Cities uses Vram for.
