Yes, Lumen (and raytracing in general) has a performance overhead. If you don't want that you can skip that feature. Split Fiction and other games choose to do so.

I think certain games like Robocop are awesome on UE5.

Unfortunately, for the consumer this can also mean skipping some games altogether: for example, I might not be able to play the latest Indiana Jones or Doom game because they refuse to let RT be disabled (unless they get enough pushback, but we can all see where things are heading).

At least there are some (usually indie) games that let you do that, like Incursion: Red River but even with Lumen and other features turned down, the performance is still worse than UE4 games of comparable scene fidelity (not necessarily complexity). I think the industry might have jumped into Nanite and all the adjacent tech way too eagerly.
