Basic things like compression can be needed for a consumer application. And it's just one example. So I completely disagree with "2 cores are enough for consumer application" idea. And it's even further form truth for games. Last time I looked at something like Cyberpunk 2077 in the debugger, it had 81 threads. 81! Part of it were vkd3d-proton ones, but only a small part. And it actually does load CPU pretty evenly if you monitor it, so I'd say it scales OK.

The data those threads are touching is just as important. Cache locality is hugely important to many game workloads.

Cyberpunk may not be an extreme outlier, but it's definitely better than the average game at making effective use of more than a handful of CPU cores.
