Really quickly because I’m about to pass out. If you suffer from the double speed glitch, here’s how to fix it.
Open task manager (CTRL+SHIFT+ESC).
Go to the Processes Tab.
While running Playonline, find pol.exe.
Right click, choose the bottom option “Set Affinity…”.
Uncheck all but one CPU.
This worked for me, it returned my game to normal speed. I’m on an AMD Athlon 64 X2, 4400+. Hope it helps someone.
