Going to bump this topic with some screenshots.
Persona 4
Final Fantasy X
Tales of the Abyss
Don't give up if you are only getting 20 FPS in games, I was getting the same, but after tweaking my config a lot I finally got games at playable levels.
Under my current config I run almost all games @ 60fps fmv / 60fps menus / 50-60fps in-game.
Tales of the Abyss ran slightly slower than the rest, but I haven't tried tweaking config to get my FPS back up there for it, although even thought he FPS is lower, it's still incredibly playable as is.
I think we should make a huge list of playable games under pcsx2 and under what setups they best run for (insert gpu here).
