I don’t think the problem is necessarily PCs being inefficient. IMO it is more likely that it is simply much harder to optimize for random hardware combinations that people run, and that there is a lot of pressure on devs to optimize console gameplay (likely at the expense of optimizing PC gameplay, perhaps devs also see less of a need to since most PCs are better equipped than consoles anyhow, that and deadline pressure)
