When playing it on the PS TV, it shows that the frame rate issues has been improved and that it would perform more smother than on the PS Vita

I also have noticed some frame rate issues, especially when in battle with several enemies on screen

The PS3 version was remastered better than the PS Vita version, so this leads to saying that the game has a frame rate issues, sometimes the audio muffles, and the cut scenes are not remastered from their original PS2 format

portable.cos.the cos are frame rate issues, graphic that aren't impressive on the vita, usage of the original ps2 fmv with no up scaling, and a few sound glitches.

(and sure it doesn't look as good as on the PS3) but you have to give credit to the fact that you're playing a game originally made for the PS2 on a portable device, it's not going to be absolutely perfect
