No, I have not disabled them. I just upgraded my OS from win7 32 to win7 64, added 4 gigs ram (8 total), my SSD/HD(not sure which one I bought when we built this machine) is only at 27% used memory (73% free space on it) Running a Zotac 1 gig video card (just upgraded to it from an Asus about a year ago) Still running the dual core E7500 intel cpu on an Asus PQ5-pro motherboard. with about 8 loud oversized cooling fans and a water cooled cpu tower.
You might be right, because forever and a day now when I select my character (even before awesomium) I get (not responding) in the window tab as the game tries to load me, I always have to minimize the client to get it to actually load. This is an *ALWAYS* deal for me since I started playing the game though, so I just never have complained about it.
