Reporting similar issues:
Extremely slow rezzing of rezzed objects (seriously ... like 5 minutes per object, at a 40 meter draw distance)
Ping Sim is in the low 40's
Time Dilation is bouncing back and forth from 80's to low 90's, with occasion high 90's spikes
If I stand in one place cam-focused on one spot, the objects out of my ROV tend to derez
Have tried some of the more typical remedies, like TPing to a different sim, dragging my cam view out beyond sim boundaries and back (effectively resetting draw and view). Frankly, it only makes it worse and reverts to nothing being rezzed and having to wait for it to rerezz
