Was playing Battlefield 4 a little while ago and my system started to stutter insanely. Check the task manager and memory along with cpu usage had spiked. Cpu was fluctuating and memory was stuck at 97-99% so I closed the game. The next hog for memory usage was Chrome so I closed that and the usage stayed at 98%. After that it's my virus protection which is topped at about 20mbs of usage. Not really even sure what a memory leak is but I keep seeing it mentioned with bf4, chrome, and windows 8/8.1. I am running 8.1 at the moment and specs are in sig. Any ideas on how I could go about finding out what the source of the usage is?
