I have 16 gb of 3200 mhz ram in my system and yeah its better... 16 gb is kinda the "sweet spot" for ram current gen. BUT I will say that you need to clear your cache if your RAM is that "full".... with that being said you usually dont want any storage (be it SSD/HDD or even RAM) to go much past 85% capacity before you see performance issues. There is a program I just found out about the other day (i was having "stuttering" issues as well in ALL games after gaming for like 2+ hours). Its called "Intelligent list Standby Cleaner". Running that and doing a disc clean clears my cached memory on the regular and I havent had any "stuttering" issues since. I searched for weeks, even taking components out of my system and replacing them with others to find the "issue". Ironically it was RAM cache that turned out to be the culprit. I literally have that program "empty" my system cache when it gets to over 5 gb (so in your case id set keep the stock 1.1 gb or even higher the program comes set at). Try and do a google search on it, read up a little on it and see if it might help. If you think it will, no harm no foul, its a free download and its virus/malware free I scanned the file twice before I downloaded it just to make sure...
