I believe the sim speed has less meaning than many ppl give it.
Yesterday i played 5v5 for the first time (on beta). The game was lagging noticably. Quite annoying but not completely unplayable.
I couldn't see my own sim speed (it just showed 0) but ppl were telling me i was in the negative and asking whether i could turn down my graphics settings. Since i do have a quite decent PC (Geforce 8800gt, Athlon X2 4600+) sigificantly above the recommended specs I was doubtful but still followed their advice. No change. Game still lagging, sim speed still crap.
After a while the guy with the 180ms ping dropped or RQed (whom i had suspected as being the cause of the lag, since all others were <100ms). And violá: no lag, smooth gaming!
Suspicions confirmed!
