Low FPS. Max VRAM & RAM. Upgrade RAM?

[sander4ajax]

Hi there,

I have an HP ZBook Studio G5 laptop, which includes an i7-8750H processor (4.10 GHz), a Quadro P1000 GPU (4GB), and 16GB of RAM.

I've been experiencing significant lag, especially in downtown areas, with frame rates dropping below 10 fps. My city has around 210k population, 8 DLCs, 40 mods (no graphic mods), and 50 assets. Even on the lowest settings, the performance is poor. When I move away from downtown, the frame rate improves slightly to around 15 to 20 fps.

During gameplay, my CPU utilization hovers around 60%, GPU around 50%, and both VRAM and RAM are maxed out at 95%.

I'm considering adding another 16GB RAM stick to my laptop. Will this increase my FPS? Currently, even moving the camera causes significant lag. I'm thinking that adding more RAM might reduce the reliance on the pagefile, but I'm not sure if the issue lies with the VRAM and GPU instead.

Could you please advise?

Thanks.

Edit: i7-8750H has a base frequentie of 2.20GHz, Max turbo 4.10GHz

The Quadro P1000 is a professional graphics card designed for CAD and 3D application. It is NOT optimized for gaming. It provides poor gaming and benchmark performance.

The GPU is holding you back....
Processor and Ram are fine. I have 16gb ram and running several hundred mods and assets (934), and get 50+ fps on average. The game slows down for everyone no matter what your pc specs after you reach a certain population number...

TIme to upgrade.

I'll go a step farther than Longhaul, and say your entire system is too slow/small for the City and Assets you want to run "smoothly".

And, I always recommend a minimum of 64Gb RAM .. RAM is cheap, get all the RAM.

If the pagefile is in use at all, then you need more ram. Full stop.

Yes, the pagefile is in use. The total assigned RAM is at the moment 25 GB. VRAM is down to 88% with a mod. RAM 97%. I get some crazy drops to 4 fps right now. :(

Cities Skylines in 1080 resolution should require around 4-5 GB vRAM or so to so your graphics card, barely meets that criteria.

RAM will not increase FPS substantially, but will enable faster loading times and better handling of larger modded assets libraries. It might help a little if your RAM has to pick up the slack from the GPU.

For higher FPS, you will want better GPU - and CPU for faster simulation - but you cannot really upgrade these in a laptop...

Downscaling the game's resolution are things you can do if you want to keep using your current laptop.

Your Quadro P1000 is roughly a GTX 1050 (released 2016).

16GB is a little low, but if you have a page-file on SSD it shouldn't be too bad.

Maybe you have reached a game limit. Vehicles only get 16k of vehicles, so when that limit is reached, it will bog your system quickly.

At 210k population, I assume it is traffic caused, so vehicles are the likely cause slow down.

Check your info views/outside connections, and make sure your imports/exports and very low. well under 3,000

Check your transportation system. excess pedestrians walking/waiting for the bus can spawn vehicles and add to the problem. Same with enabling bicycles, as they count as vehicles.
