@Gednaa Your Mac's graphics card is not upgradable, neither the card overall nor its VRAM. If you think the VRAM is limiting performance, you could try playing at a lower resolution, which would use less video memory overall.
In theory, you could get an eGPU enclosure and a standalone card to go with it. In practice, this is a terrible time to buy graphics cards of pretty much any kind—demand is high and supply is snatched up minutes after appearing. So unless you want to pay double to a scalper for a 5700XT or something, it would probably be better to wait a few months.
@Psychotps Since you're into making mods and generally messing around with game features, do you think disabling a few components of Eco Lifestyle would help performance? I'm thinking specifically of the visual effects of a green or industrial footprint, but there might be other elements that are worth poking at too. (Applying the NAPs seems like it would be mostly CPU intensive and spare the GPU, but that's easy to test with in-game settings.) I would guess that like most packs, there are only a few features that have an outsize effect, and the rest are negligible.
