To add something constructive to the thread, playing on my old computer (Dual Core 3,0 Ghz; 2 GB-DDR2, 8800 GT) I have in my holiday mansion I spent last month, I noticed receiving a (very) small lagg in open range whenever someone with Hermes came into draw distance, also taking FPS down from 30-35 to 20-25 for around a second or something like that. It never happened with Infiltrator or any other armor, just Hermes, so perhaps it's the same with Carramone or any other item star actually is randomly wearing / using causing a small lagg when entering draw distance.
Also isn't that kind of unreasonable since MA is still working on fixing such performance issues. EU runs much more smoother now that right after VU 10.0, at least in most cases, maybe some kind of special armor, clothes, weapons etc. still causes a kind of (very) small lagg, if you remember, some mobs did too at the beginning of last month which got fixed in a 10.0.xx VU.
