Oh, that's the sim limit on avatars for the sim I RP in. I never wear that much either. The only thing I ever wear that's scripted is the collar and I always hover between 30-50 scripts because of my Open Collar scripted collar. I don't wear huds save for my AO unless as needed, like if my character is doing something in RP. I delete resizer scripts after usage. I don't wear bling - its awful. I don't use sound scripts or wear things like walker sounds or anything. I try to keep myself as minimal as possible because of the scripted collar.
I don't have issues on sims until I run into places that are heavily sculpted, done all out with light beam pims, or have lots of detail. There might not even be any other avatars around, or there might be tons around. It has to be my graphics card.
I did pull up my statistics bar the other day and when I went into one of those areas with the grass all over, prim fog, and the glowly lights my FPS dropped down to like 1.2 from 20. This was on low graphics with minimal draw distance.
