In theory, if I have configured the public node network correctly, old versions of The Qortal Core, will update upon reaching the update-approval block (meaning, the block that the dev team ((with 20% agreement betwixt them)) decided to 'approve' the transaction, thus making it a permanent portion of the chain, and setting a block by which updates will take place upon any node synchronizing as far.
Essentially - IF YOU'RE ON AN OLD VERSION, IT WILL AUTO-UPDATE IF MY NETWORK IS SETUP CORRECTLY.
Running qortal-1.2.2 now on 64-bit WIN7 and CPU usage is still over 50% on old i3 laptop. Because I'm not running anything with administrative privileges, real loop show starts when right clicked on qortal taskbar icon and start Synchronize clock. Don't do this at home...
Please someone look into this ....
Facing this issue since Genesis....
I would have understood if CPU usage is increased when finding the node etc
But the issue his... CPU usage is high all the time (Post some time after the node is started) irrespective of how many nodes the core is connected to.
