The only real limit will be down to your hardware.
Anyone else excited for City Skylines 2? I'm pretty impressed with all the changes they've introduced, it should be a more dynamic experience this time around.
With the focus on scale, I'm keen to see how performance goes this time around. I remember in previous huge cities it could start to chug.
I'm assuming we'll get at least FSR / DLSS upscaling support this go around too?
