I played the beta for the first time last night and noticed an intermittent pause every 10 minutes or so. The game would just hang for about 30 seconds and then things would start moving again. My system specs are as follows:
Windows XP, Intel C2D E6600 Processor, 4GB RAM, GeForce 8800 GTS 320 MB (Updated Drivers), Cable Modem Net Speed
Maybe my specs don't support the game, not sure. The graphis settings were default, no AA or anything.
Thanks!
