BritishBean the target with PS5 games is to be loaded in under 2 seconds, they will also (allegedly) be supporting direct launching in SP, MP, other straight from the dash. So my point was that this is going to be quicker than dumping memory to disk and loading in full memory again. With very few button presses.
For XSX/XSS quick resume of b/c games will be much faster than loading from scratch, so that’s the best way for those. For XSX/XSS optimised titles it may be quicker to boot from scratch too unless you want to come back directly to where you are in the current title when switching.
