I can't figure out how I'm using 80% of my ram. I have 8 GB. The Witcher 3 is currently using 2540 mb, I've only got 5 Chrome tabs open, Steam, HWMonitor and a handful of background apps but I can't see how this is consuming 6.5 GB of ram. How can I find out what's consuming so much? If games start using more than 2.5 GB of ram I'm going to run into trouble it seems...
