My wife and I each have our own gaming rig and we have played a ton of games without issue. However, trying to party up in D4 isn't just laggy, it's unplayable. I'm talking jogging in place for minutes at a time, can't interact with doors or equip armors, completely busted. Solo play has what I'd call "normal" lag but nothing like being in a party.
Cross play and Cross platform chat are off. BNET launcher is closed. Updated drivers, etc. No torrents or VPN or anything like that running. It's got to be server side right? But if everyone's experience was as awful as ours I'd expect to here much more complaining. Anyone got any other suggestions?
