Today I was as always trying to find a way to improve the sim performances and had a look at the Statistic window of the viewer and saw something that did not hit me before.
KTris per frame AND Total Objects. Found out that in SL the viewer only consider Object that are in sight, but in OpenSIM it kind of always mention all the Objects that are in the SIM, I'm not sure if it is real or if it is simply a bug on the viewer but what is more alarming is the KTris that is so amazingly high near the Palace.
I had like 1200 KTris per Frame in the entry of the city and reach 15000 in the Palace.... So I found another way to mesure the LAG issue near the palace. I then went to Second Life on Rose Theatre to compare and I was at 1234 KTris...
I will work harder on reducing Polygon Count on the Palace so Lag should reduce also and will work with this stats for now on for testing.
