FIrst hello dead islanders..

i purchased the ps3 version of riptide today.. played for about 4 hrs so far and theres some issues i wanted to let you guys in on also to know if anyone else has had these.

first.. the crosshair is so light in color it becomes pretty much invisible as you turn and move around the world, anybody else noticed this ?? this is very annoying

second.. im getting alot of lil freezes, they are like a split second but once you notice it.. it becomes very distracting, as you can see the micro shuttering happening constantly.. is it caused by sudden frame rate drops in the game ? 

i loved the first game and i know the reviews have been very mixed but i still wanted to check this out, the first game never had any if these issues.. well for me and its very disappointing that two issues can really ruin this game, im sure ( hoping ) they will fix these issues in time but jst want to share and see if you guys had noticed these.     cheers,

ps.. on another note, does anyone know if the world is seperated hubs as like the first ( i preffered that ) of one just large continuous world
