Yeah, browsers can be great for causing stutters even if there is no video on the page so sometimes I have to restart a browser but not often.
As for CTDs, they shouldn’t cause that but I guess if a system is less stable than mine it possible it could CTD. A lot of gamers like living on the edge of performance and tweaks, and I bet many of those are the ones with the CTDs.
120 hours of play so far. Not one CTD. Though I only fly the GA machines, maybe the heavies can cause them.
