I'm playing Jak & Daxter trilogy on Vita and the games are awesome; hardly any slowdown sofar.... It's not as good as Sly trilogy, but not that far of.
Weird because alot of complains were made about this trilogy.
I have a question, did you ever play the original PS2 versions or the PS3 Collection prior to playing the Vita Collection? Because if you didn't play those versions in the past, you are experiencing a 60FPS game running at a mostly consistent 20FPS on the Vita :l.
I never played the Vita Collection (though I plan on doing so at some point...), but everything I heard is the following:
-Jak 1 runs at a locked 20FPS ala OoT/MM with frame-rate drops in Sandover Village; the game runs better as you progress
-Jak 2 has bad slow down when exploring the city, but in loading-areas or small areas, the game runs a smooth 30FPS
-Jak 3 suffers the worst reportedly; many areas of the game run under 20FPS and it can reach in the tens if you are doing to much.
The games look great on Vita however and Jak 1 controls well (considering you do not need L2/R2/L3/R3 in the game). The important thing is that you are having fun with the games, and that's great
; Jak 1 is one of the best platformers out there and Jak 3 is a personal favorite for me
.
If you never played these games on PS3 or PS2 before, please consider getting the PS3 Collection or the PS2 originals; they run fantastically and with the higher frame-rate, you have a much more enjoyable games on your hand
.
Hope this helps you
