It's strange to think about Consoles, PCs, and Ports. Consoles were nothing like PCs for a long time, so ports took actual effort and reduced cross-platform releases a bit. Then consoles started to look and act more like PCs and porting was relatively easier until the hardware started to diverge into the powerful, combined SoC systems we have now compared to the sturdy-but-separated PCs that haven't had a major form-factor change in 20 years.
So PC ports are less efficient because they don't have such continuous, low latency access to memory and the best solution (cheapest?) is usually to just dump everything into VRAM and require more memory. It's frustrating when you can buy a game on a PS5 and it plays great but the PC port needs at least double the specs to run well.
I guess PC gaming was kind of always expensive on the high end but the low end is just disappearing entirely when devs aren't allowed to spend time optimizing at all.
