Depending of how many cores your CPU has set Affinity on the first process of swtor (the one with the most RAM used) to either 0 and 1 and the next process of swtor.exe to 2 and 3. Now find your Buddywing.exe process and set the affinity to only use 2 and 3 core ( same ass the second swtor.exe ) you will find the stutter going away.
This setup is for quadcore if you have dual you will set it to 0 for first and 1 for second and buddywing.exe.
This actually works. Taskmanager. find swtor processes. Right click, Set Affinity 0 and 1. find other swtor process. Right click set Affinity 2 and 3.
Find Buddy wing process. Right click and Set Affinity to match the swtor process w/ the lower cpu usage. tadaaa.
I thought bullshit when i read this. But not so.
The reason it works is that SWTOR likes using more then 2 gigs of RAM if it is available. So they spawn two processes for the game to get around the 32-bit 2gig limit. Forcing the affinity across both processes means that the OS can't accidentally put them both running on the same core(s) (which is what causes the lagging when BW is then involved).
i cant change the affinity :S it says : the operation could not be succeded. Acces is denied :S
That's a Windoze bug, IMHO. You have to select "Show Processes from All Users" in the Task Manager, before it will let you set the process affinitiy.

btw i'm wondering, will it remember the affinity changes when i start it next time or is this something i have to do each time?
