I have even tried tieing the coresync process to just 2 cpu threads using project lasso by Bitsum, with no relief. I am still able to use the software from CC of course, I just need to be sure I then go and force quit the coresync and related processes once I am finished otherwise my computer simply slows to a halt. I have written an autmation script to close these processes with one click to make it easier for myself, but why should it come to that?
This issue has been plaguing Adobe CC for so long now, it is almost becoming acceptable to put up with it... much like Windows and the BSOD.
Please Adobe, I beg you, fix this annoyance once and for all or find another way to achieve what coresync is trying to do, but without the resource hogging!
In the mean time, if anyone has a surefire way to fix this issue, not just "bandaid" it, please share it with me?
