A few random thoughts from having used my PS5 for most of the day yesterday:
o The console is definitely big and chunky
o My PS5 remained quiet and cool during use except when installing or verifying game discs. The former is noisy, on par with my PS4 Pro, but the latter is just a mild hum or clicks for a few seconds. Since you only install games once then this isn't an issue.
o PS5 starts up really quickly, like 2 seconds from Rest mode. V. nice.
o The Home screen and new interface are very nice, although the way the PS button now works takes some getting used to. Tapping it no longer returns to the Home screen (you have to hold it down) and instead takes you to the quick access bar instead.
o Operating system seems to be a bit buggy. Got lots of install errors when I turned it on with my 4 TB external drive with all my PS4 games connected. Seems like the PS5 cannot handle too many simultaneous downloads. This resulted in me accidentally deleting some of the games on the external drive when I used the Cancel and Delete option to clear all the errors. Deleted Red Dead Redemption2 and Ghost of Tshushima this way and probably lots of other games too (still need to check what is gone).
o The way the PS5 defaults to PS4 games is annoying. I was initially baffled as to why Sackboy was playing a 10 minutes graphic novel that I thought was an introductory cutscene until I realised that this was not the actual game.
o I accidentally deleted some PS4 games because some games showed both a PS4 and PS5 version so I thought I'd uninstall the PS4 version to make space, since I why would I want to play that version? I ended up deleting Spider-Man: Miles Morales this way. I would be better if the Home screen showed separate icons for the PS4 and PS5 versions in my opinion.
o Downloads were initially very quick - the PS5 internet test showed 212 Mbps down and 33 Mbps up on the Wi-Fi connection (of a max 420 Mbps down and 35 up) - but then slowed down to a crawl during the afternoon, no doubt because the servers were being hammered. This resulted in game patches for all the launch titles taking much longer than expected. Frustrating but not unsurprising, I guess, for launch daY.
o The DualSense controller is amazing. The haptic feedback is neat, especially in the showcase Astro's Playroom game, but I'd already experienced similar on the Switch so it wasn't that amazing. However, the adaptive triggers are revolutionary in my view; I was really impressed with how they worked with the springy section on Astro. Really, really impressive and coupled with the way sound and haptic feedback works makes for a really impressive controller. L1 and R1 also feel much less sticky and, thus, more responsive plus I really like the new D-pad. Feels much more comfortable and quicker to use than the DualShock 4's.
o Not had any problems so far using the Resume and standby features with the external drive connected. I did have one instance where I went into Settings > Storage and the PS5 did not show the external drive as already connected but games still showed in the library and there was no error.
o Ghost of Tshushima in Resolution mode at 60 fps!!! Wow, it makes Assassin's Creed: Valhalla look dated in comparison.
o Not sure if it's me but disc installs seem to take noticeably longer to install on PS5 than they did on my PS4 Pro as if the drive itself reads slower (maybe because it is a 4K UHD drive?).
o Loading times on the first party games is amazing. After the first boot, subsequent loads seem to finish in the blink of an eye! This does make the third-party loading times more disappointing though; why does Assassin's Creed: Valhalla need loading screens?
Anyway, this seems like a really great console so far although like with the PS3 to PS4, there isn't that massive generational leap visually. It's more a refinement of what we had before with higher resolutions and more stable framerates. Sackboy and Spider-Man: Morales all look fantastic on the PS5 but not a huge leap graphically (although the ray-tracing is nice in Miles Morales but you have to sacrifice 60 fps to use that)).
The big bonus is being able to run all PS4 games on PS5 which addresses wonky framerates in every game I tested. I think that really adds to the value of the PS5 when you can still play all your old favourites with better framerates and higher resolutions.
