Quantum Break had occasional performance issues but that's something else.
Does this include Xbox an PS Slim versions or just launch consoles?
Both games are using the same engine, which also happens to favor their own house made "reconstructing" technique, which does come with a performance impact.
This easily reminds me of RAGE 1 using megatextures, which came with all sorts of issues. I really wish devs would stop trying to invent new ways to show you an image, that inevitably ends up hindering how it's displayed in the first place.
PC performance is also in the crapper as well, since even the RTX 2080ti has to turn down settings and also having to rely on DLSS, just to stay roughly at 60.
Dump the engine, it's clearly not perfect and it's clearly not working well with all sorts of hw out there, consoles included.
