I first realized this a few months back, but I just remembered it. If you want to play a WG.net game below the minimum requirements, I know this may sound weird and counterintuitive, but DON'T set all graphics settings to low. For whatever reason, the computer will usually react the same to that as it would changing the screen quality from the computer's innate settings: it'll go haywire. Trust me, I know. I've had it do that before in WoWS, and my below-minimum requirements laptop's current issue with WoWP seems eerily similar.
I have no idea why this can occur, but just a heads up. Just letting you know what can and sometimes does happen..
