I've just had my first stint on this and it seems decent enough I ain't absolutely blown away or anything but I like what I see so far, It certainly seems to hold its own with the other Racers but I can't compare it to GT4 as I don't have it nor have I played it.
The framerate seems to run a little lower than some other racers (i.e. Rallisport 2) at times, but you guys already noticed that in the Demo which I haven't played ... so I can't say whether its been improved since that version or not.
What I can say is that it never gets low enough to spoil things from what I have seen of it so far. In fact to me the framerate feels almost exactly comparable to PGR2 which never seemed like it ran anywhere near 60fps more like 30fps ?
Anyway I firstly went into Arcade Race and took a Big 'Ol Black Bentley GT for a spin around the first track ... "Maple Valley II" a Tarmac at Dusk affair ...
First thing I noticed was a lot of Assists available to help out a Rookie.
The best one being the green "Arrows Raceline" on the track which when you are going too fast glows Red until you drop some speed upon which it returns to Green letting you know you are doing the right speed for that corner/bend, As I say a good feature to the not so "Sim" friendly newcomers ... managed a second place in the Bentley then I switched to a Yellow Porsche 911 GT3 and managed a first 2 laps later.
Other things to mention that I liked ..... The Graphics, well they may or may not be better than GT4's, you tell me ? but they are certainly more than capble of supporting this Game and what they certainly do have is a nice "Style/Look" all of their own and they've also flung in some nice lighting and shadow effects on the models and the track.
Also of note are the Damage effects on the cars, very smart and a lot more advanced than in any of the other racers this side of "McRae/Rallisport/Burns". I had some nice scrapes & cracks on my Vehicles by the end.
Lastly, for those that are into their Stats and Data you have the Telemetry options on the Replays ... Pretty Advanced ... it lets you see in Real time all the Data of your Racing/Car at that exact second in the Race ... Cool Feature for those that want it.
Well I've rambled on for long enough, probably telling you everything you already knew from playing the Demo. ;-)
Anyways hope my impressions were the sort someone was after, just told it as I saw it
Cheers Guys
