Hello,
While this is perhaps not the best place to post this reminder, and fully understanding that there are 2,000 or so sims to re-check right now, whenever possible, I'd like to ask you to take a look at the subnormal performance at Io. Sometimes ping time "spike" up for several minutes, causing FPS below 1 (even on above-average machines), even with just a single avatar, and the "usual" number of scripts running (~300 on 1.6.12 statistics, ~1800 on 1.7.0).
Even in 1.6.12, there were "script spikes" here and there (so I guess it was a recurring problem, something that just degraded much more intensely with the 1.7 upgrade), but performance was relatively acceptable.
Thanks for any insights on this!
