Running a 4man group on 457 seems to be using up about 50-60% of my PC's resources which is about normal since I run 30 TPS on all of them and I don't modify my D3prefs just run medium to low settings.
It does seems like I get more slowdown and lag on my screen when a lot of effects are happening, but that could be attributable to the D3 servers and all of the crap my bots are spamming all of the time.
Anyone else experiencing slowdowns?
