do you remember if that's an apples to apples test? Same cars, same weight as before? From what I cna tell, weight matters more than anything.
I did a test on Nurb Nord with an Audio LMS TEam Playstation which someone bitched about on the PSN forum after the previous update... one lap going balls out and they were down really low. No way to get two laps. I tried again the night of this last update (2.04) and I'm not sure if I drove exactly the same (I think I held back more) and I was able to get about 1.7 laps before all control was lost and I had to quit race entirely.
Here's the issue though...
With the "NEW" tire wear model from a couple months ago, The tires wear faster, but they also provide grip longer through their lives. Before, you had to pit if you were at or just below half. Now, you can take it easy for a while under those conditions and survive.
So I'm not REALLY sure that it changed with 2.04 because my previous test of 1 lap on Racing softs around Nurb might have been cut short by me not trying to continue on tires that seemed too low to continue, but may not have been.
