Oh my god, swinging around on Skyline = Mind Blown!
No frame rate issues on PS3 so far. There is slight tearing which shows that adaptive Vsync is involved.
The city is fully explorable. Every nook and cranny can be search to find secrets/hidden extras, of which there are plenty. Gameplay wise, the shooting might not be the best part but the abilities make it ton of fun along with the melee moves.
I tried unlocking the frame rate and the game felt like it was running on Turbo, lol. But of course, there was loads of tearing with unlocked frame rate. I don't have any issues with locked since the frame rate is pretty steady and there is hardly any stuttering.
The only minor qualm is some low resolution textures along with low quality effects at some place and since it is a pretty big city with impressive draw distance, it means that with no powerful AA like on PC, we can notice jaggies in the distance. Regardless, it is certainly a looker and as a multiplatform title on PS3, it has pretty neat IQ and solid performance level.
P.S The city is not fully explorable without any loading. There are large open areas that are linked with each other through a door and upon entering them, we do see a loading screen so it is not seamless full world exploration in a sense but it gets the job done.
