Just as my title says, recently my PC has been having issues with high amounts of RAM usage, the use of which doesn't seem to match up with what's shown in task manager. My computer has 16 GB of RAM, and if more in-depth specs are needed, I can provide it.

I have ARK open in the relevant screenshots, so I know that is using a lot of memory, but it never used to be a problem. Here is my Task Manager and RAMMap screenshots. I feel that 2GB shouldn't be the dark orange that it is in the Task Manager. If I'm wrong, and there is no problem, I have no issue installing more RAM, but I wanted to check as I've had issues with memory leaks on my computer before. I just cannot seem to figure it out this time and don't really know how to read RAMMap.
