They “could” throw a performance mode out to shut up the noise, but it would be wildly inconsistent, and probably not worth anyones time. Did you watch the digital foundry video where they compared it to start citizen? It’s very informative if you care enough to take the 15 minutes to check it out.
From a developer standpoint it makes the most sense to make a stable 4k/30fps mode the best it can be, than it does to have a raggedy ass “performance mode” just to appease forum dudes on the internet.
