I'm putting this here as well, just in case it catches the attention of someone able to help.. 
It seems the Enhanced Client doesn't agree with my rig and I can't really see why.. There's no Lag when I'm not FreezeStepping and it's all UO; There aren't any other issues with any other application. What information should I gather to begin looking into this?
I think it's related to what's in view as it seems to get worse the more Housing or NPCs/PCs are present. But I'm not sure and I definitely don't know how to fix this. UO has never acted up like that before.
