Over 2 hours of gameplay the amount of ram used by insurgency went from 785,000 kilobytes to 6,700,000 kb in my windows task manager. This ends up with my computer saying its using 99% of my ram despite the fact that when you do the math it should only be using 80% of it. It might be caching the ram or somthing idk.

Yea it's at 98%+ for me all the time, eben though CPU usage is like 20%. I have 16 gigs of ram too, I don't get it.
