1. Dual core here laptop lol. 2.5ghz 4gb ram 8600m gt nvidia
2. normally 95-100 % but still is playable havent tried dalaran kinda scared haha.
3. Graphics set bare minimum
4.I have my 5 instances on both all 5 are being split on both cores. So 1.2.3.4.5 are on both core 1 and 2 did that and the 95-100% went to 80-90%
5. Main is at 35 fps slaves 10-15
6. symlinked never got into it
So thats it for me it works but buying a quad core desktop to run slaves on so they all get 30-40 fps and run main on laptop so i can have settings set high.
