Here recently, I been experiencing weird intermitten lag when playing DDO.
The game (and my machine) starts lagging out really badly for around 2 minutes and then it clears up for 2 to 5 minutes and restarts again. It has happened several seesions now and it ONLY happens when DDO is running. I experience absolutely no lag with any other games or applications on my PC.
I even shut down everything I possibly cood in task manager to see if that clears it up. I also updated my Windows and Rebooted and cleared my cable connections.
