Hi, When I load World of Warcraft the CPU jumps from an average of 10-15% up to 100% and stays there pretty constantly whilst playing. This doesn't seem to affect gameplay most of the time (and I understand it may be relatively normal behaviour for running games under Wine), but occasionally I get a complete lock up of the game for about 3 seconds. The game screen freezes completely and the sound stutters during this time. These stutters very often follow a mouse-click (for instance when selecting items, or speaking to NPCs), but not exclusively - the game also sometimes locks up while just running around. Also no difference between left or right click for the frequency of the problem. My frame rate is fine, maybe 50-70fps on average, and my network lag is also fine, about 40-60ms. I'm running 32 bit Ubuntu Gutsy 7.10 on an AMD 64 3500+ with 2GB RAM, using an Nvidia GeForce 7600 GS. I have disabled all my Addons to see if that helps, and it doesn't. I have also added the Wine registry edits and config.wtf amendments suggested elsewhere (particularly in the WoW Wine Wiki). Any ideas? Or any other info I can provide? Many thanks in advance.
