I saw your post regarding the trees-based world performance, and also
just hypergridded Cyberlandia as follows:

link-region 1000 998 grid.cyberlandia.net:9000:cyber

and turned on the stats via Ctrl-Shift-1  and then teleported there. 
This world seems to
offer enough complexity to test out a few features of the modrex'd viewer.

When switching within Rexviewer (Shift-R), you can see an FPS difference
in performance of anywhere from 7x to 10x for the LLviewer. Using modrex,
I am unable to change the graphics settings (for example, Preferences->
Graphics->QualityAndPerformance slider isn't doing anything), as I am 
sure that
tweaking these might help users adjust the performance tradeoff.

perhaps, there could be a set of "recommended settings" for opensim worlds.
