I've been having a little bit of an issue running CS:GO. Whenever I play, at times it will be good, but then all of of a sudden, it will just get real blocky and laggy and my computer will start to freeze up. Is there any way I can fix this? I have all my settings to the lowest possible one, but it is still doing it. And it is constantly eating up all of my CPU and RAM when they claim it can be ran on an old crappy computer.
