I am going to buy a budget pc with spec
Ryzen 5 2400g, No gpu, 8gb ram, 550w psu
I dont plan to mod yet.
How many population / land mass do u think the simulation start to slow
Thanks
The 2400G is a 4-core/8-thread CPU and the game is designed to use a max of 4-core/8-thread CPUs. So you should be fine.
8GB RAM is very little for integrated graphics (iGPU). Your graphics will consume 3GB of that memory off the top so it can run the graphics. This is a big reason why iGPUs aren't typically supported, as this can cause a lot of issues. Now you are left with 5 GB of usable RAM. This is going to be a chore for the game to run effectively, especially as your city grows. The base game alone uses over 10 GB of memory. That is twice your remaining RAM.
Also, memory speed and type is important. You have 64-bit memory which is low volume, plus it is very slow DDR4 memory. A dedicated video card should have 128 bit memory bandwidth, so it will process twice the data. Plus GDDR5 video RAM (vRAM) which is significantly faster as well (approximately 3 times faster.)
Too bad you didn't keep your GTX 650 Ti Boost. It would be much faster than iGPU and not use up any of your precious RAM. If you can get it back, you will be golden.
Not sure if you can return your RAM and get faster, then you can get better performance. I went from DDR4 2133 to DDR4 3200 and got about 50% more performance and from a little lag, to almost none except busy areas. Plus I overclocked the iGPU and I was lag free. I had the 2200G (4-core/4-thread)
You should do quite well on your 2400G, than I did on my 2200G. You should get a full 9-tiles with a little lag. But it should be playable.
Definitely avoid the workshop completely.
If you haven't purchased it yet, I'd replace the:
2400g, with a Ryzen 1600 (or 2600 or 3600, they are the same 6-core/12-thread CPU with slight improvements to each generation)
16 GB RAM with 3,600 MHz speeds max. 3,000 (2,933 Mhz) MHz min.
A Radeon RX 570 4GB dedicated GPU or better.
