Since Thurs of last week, the game is a no-go for me. I had 35-55fps, and the occasional lag/low fps, before, and now after log in, within 5 mins, my game goes from that 35-55, down to 5-8fps, and stays there for over 10mins, to which it will go back up again, and then down, then up. I have even played in a windowed view, with half resolution selected, and still persists. Done a traceroute, closed off other programs(Norton), turned most of the option to almost nothing, still a no-go. I'm not sure what they do with these patches, but it seems more n more, I can only play less n less. So glad I went gold this month.
That sounds like an overheating graphics card with a failing fan. You might want to download SpeedFan to check your GPU temperature. I know because I had a problem like that a couple years back. It happens; fans go out and need replacing.
As for disconnects, I've been having a few odd random disconnects here and there, usually during zoning, but nothing as frequent as what I've seen described in this thread. So something's twitchy somewhere.
Yes, I am having the same issue as well. i performed tracert and nettest the results are excellent. my system is very stable and fast, my isp is cable (20mbp dwnld/17.4mbp upld) is good as well. running diag on vidcard see's nothing wrong either.
I've done everything i can here, any other ideas?
