That is an insane amount of RAM. I checked a lot of the tech demos and they blew my mind. To think 10-20 years ago we were happy and amazed at the graphics then. UE5 might be one of the biggest game changers yet.
I guess in a year or 3 your tech will come far enough and cheap enough that you can take your whole project to UE5...
Best of luck with all your game making man!
