I went to the "
FTLO Ice Fest" (this is the closest I found to "FLTO Winterfest") and moved around the sim, even flying around to be sure to rez all objects, then landed close to the center of the sim, with draw distance set to 256m and all other graphic settings maxed out (with the exception of Sky, set to Low, since the only noticeable difference between Low and High sky is a drop in FPS). There were 10 avatars in the sim (mine included), and I waited there several minutes (around 10), then looked at the memory usage: 900Mb
See the attached screen capture if you don't believe me...
EDIT: waited 10 more minutes. Here is the new screen capture, with only 830Mb used (and 12 avatars around)... I also expanded the textures stats in the stats floater and as you can see, it's all good (less than 320Mb of decoded textures for around 2500 known textures in sim).
