I concur with your answers on #1 and #2. Thanks especially for listing the ram available to the PS3 as I was unaware the GPU was only able to handle 255mb.. That seems surprisingly low but explains why an Nvidia GTS259 (capable of up to 1GB of GPU ram) would obviously perform better and it's safe I say that the actual functions of the game operate mostly well, with exception to the culling priority, so it's not to say that the game is broken for us PS3 players.

I also had already assumed that the Ethernet port on the PS3 was capable of a gigabit transfer rate but still wonder if therein lies some sort of hardware limitation as for instance at any given time in my home, my PS3 is the only device hard wired to the router with all PC's and other devices being off throughout the day.

You're also probably right a out he engine being optimized for PC Users though I do hope the PS4 version comes with more engine compatibility.

The last tidbit of advice regarding targeting made me laugh simply because my first response to it was "We have to HAVE a target first in order to toggle through them with the trigger buttons".

P.S.
When I press R1 while in combat I would assume this would toggle a target from one to the next (assumably to the right), but all it does is toggle the next crossbar in my UI. Am I doing it incorrectly?
