Re: during game slow increasing lag

I think your PC is on the bottom end of the minimum system requirements, and your processor speed looks like it is below the min specs for processor speed which may be the cause of the increasing poor performance the longer you play. Have you dialed your game settings back to the lowest possible and tried playing then? Here are the minimum and recommended system requirements:
