I completely agree with the graphics part. COMPLETELY. YES. It is so hard to not be able to target people when s/he is seriously invisible to you. And if s/he's in your party list but you can't target his/her name because they're invisible. So in a sense you kill your team mate with out meaning to. You get the blame for it.

Casting. You'll get stuck with just having your character freeze until you sprint.

You get attacked by things that are invisible and you can't fight back because they're not there. It's redonkulous that it (monsters) doesn't want to load.

When loading or skipping cutscenes it takes twice as long than I guess PC.

I tried to contact with support about this but all I got was:
Fix Firmware
System update to latest
Re-install game
Firewall

Seriously its none of the above.

I play this game with my bf. He uses PC, I use the Ps3. I can see the huge quality difference and it really upsets me that I'm slowing pretty much everyone down or that I'm killing everyone.
