A new beta version was introduced recently.  This platform was added for the new game , 'Raid: Shadow'.  Like any new feature, some bugs are expected.

Detected  faster, higher graphic card memory use. It is more than before on previous Plarium platforms.  For some systems, this may cause graphic card overheating .  Please check this on the test servers asap.  

I saw this type of problem before, when Blizzard Co.  introduced 'StarCraft2' .
