Don't worry, considering the general level of optimization on all platforms and performance issues, you'll have just screenshots on your screen instead of the gameThe RTGI looks really nice IMO, but yeah, we'll see how they go about implementing it. Wondering if a form of RT comes to console as well (I'm personally hoping for RTGI on PS5 Pro so I can make more beautiful photos).
All this is of course nothing more than an advertising campaign on the part of Nvidia, I hope this is not their priority and they are busy with more important things, and they definitely have them.
