For the release candidate on Le Tigre we have some new information that comes from the wiki release notes just recently updated. Some of those are:
The Havok Physics Engine updates to version 2012.1 in the release candidate. In week 35 I reported that this version was coming. At the time we had just updated to 2010.x, I think. This update enables Havok’s terrain optimized that simplifies the physics shape of the terrain for improved performance. This feature can be disabled by region owners and estate managers with the Region Debug Console command “set optimize_terrain false“.
Some are reporting vehicle crossing are slower.
llGetSimStats() has yet to show up in the Linden Scripting Language (LSL) pages of the wiki. Fortunately the release notes say:
Currently, this function accepts only [[SIM_STAT_PCT_CHARS_STEPPED]] as its parameter, which returns the % of Pathfinding characters skipped each frame, averaged over the last minute. The returned value corresponds to the “Characters Updated” stat in the viewer’s Statistics Bar.
