I decided to try the new GTA Online, PS5.
46 seconds from launching until I had control of my character, tried three times, all exactly the same. On the PS4 Pro it took several minutes, and always seemed to vary.
Fidelity mode is approaching how good it looks on my RTX 3080 gaming PC, but with noticeably worse textures in places and some of the more involved effects like water looks worse. It's much better than the PS4 Pro however, IMO. Performance mode and Performance RT modes are very similar, I prefer RT - it makes the city at night pop just a bit more.
The adaptive triggers default settings have way too much resistance IMO. I had to turn it down to low. It was like a finger workout after a few gunfights. Had to stretch my hands lol.
Bouncing in and out of jobs is pretty much instant now. It's even faster than on PC. I also haven't had any of the weird connection issues I used to have while joining jobs or enlisting people.
Overall not bad. I am surprised Rockstar actually did a pretty good job on this upgrade. I was expecting merely better load times really.
Edit: The DualSense haptics are pretty good as well. Nothing ground breaking. I dig the way it replicates the feel of the terrain you're driving on, or the idling rumble of an engine.
