I did some testing on Poser 7 importing Sidney. Now I did not use the SR1 update since e-frontier mentioned there were problems with it so I don't know if that caused  any problems, but the following are the results I sent to tech support at e-on. It would be interesting if someone could confirm these figures.

"I ran some tests with SidneyG2 from Poser 7. I did not use Poser 7 SR1 because of its defect. I am waiting for update on SR1 which is being developed. I did use the new character updater.

I did not use any scenery only the default in Vue.

On my first series of tests I used only Vue controls. I did not activate any Poser controls on import. I dressed Sidney with a tank top and jeans. The resources when opening Vue 6 I were 90%. I have 4 gig memory even tho' I know all are not used.

Sidney with regular hair import 68% memory
rendered at 72 in window on final 68% memory
deleted Sidney and purged and flushed 78%

opened up Vue again memory 90%
Sidney with strand based hair import 35%
rendered same as above 33%
deleted sidney 29%
flushed program crashed

Using Poser import controls (I can provide you with screen captures of the import controls)

Always close and reopen Vue

Sidney regular hair import 64%

Sidney Strand based hair import 36%
flush history 33%
delete figure 32%
flush history 46%
purge memory 51 %

This is only one figure each time with no Vue scenery. Isn't the memory very low?"
