I didn't think above 5400rpm worked?
It works, its just not "recommended".
Well that was an utterly anticlimactic night for me, an hour and a half after first putting the disc in, updating (and failing, twice) then finally installing what I am left with is a slow, unresponsive and somewhat buggy interface.
Once I actually got down to some racing I don't feel any better off than with Forza but it's early days yet and I will definitely stick with it.
/edit
first night report:
So, first night playing GT5 and I gotta say I'm hugely underwhelmed. I pop my disc in and the first thing it wants to do is update with a 133mb file so I let it, this fails 3 times before it finally goes through and installs, so thats 20mins down.
Moving on to the actual install I kick it off with the timer saying 20mins which I thought was fine, 45mins later its just finished up and I can finally start playing, but wait, something isn't right, the menu's aren't loading up properly so on the "start" screen I am sitting there waiting almost 5mins just for the cursor to come up so I can pick GT/Arcade/Options. Finally I can start doing my licenses and some actual racing, wait, what's up with this ****ty ps3 controller? Its about 2 sizes too small!
After reconfiguring the controller for Forza controls I am set to go and I went through the B license mostly silvers/bronze, I will re-do to get all golds I just wanted to unlock some races. I did a couple of races and I'm pretty happy with what I've seen, I'm not bowled over or amazed which is sort of what I was expecting but it's not leaps and bounds ahead of Forza but it is early days, I've only put in a couple of hours on it so I am expecting better things.
Overall I am disappointed, it seems unfinished, all the attention has been placed on the driving experience and the menu system seems like a bit of an after thought at first impression as it seems very clunky and cluttered, I will however stick with it and I'll be playing it a lot as I've got a 3.5 day weekend coming up!
