I've been playing on the PS3 since patch 2.4. Loading times were really awful. Teleporting to a city state could take anything between 30 and 120 seconds. Retainers sometimes took so long to load that you received a "time out" message. I didn't do any hunts or large FATEs, because I could never get there in time, and when I did get there, the monsters didn't always appear on my screen.

Then I replaced the hard disk with an SSD. Suddenly loading times are measured in seconds, and I'm nearly always the first one to finish loading an instance. I can teleport as freely as PC players, retainers come in a couple of seconds and I've had no problems at all in FATEs. The only remaining problems are S ranks and the Odin FATE, where the PS3 hits the maximum on-screen character limit (so some players become untargetable).

Make no mistake, it is incredible what Square Enix has been able to do with the PS3. I'll upgrade to PS4 only when they drop PS3 support.
