Pagefile Usage

So I am in the process of trying to figure out why my Titan-X SLI won't use 99% GPU usage with my i7-6700k in Witcher 3.

In doing so I noticed my Pagefile usage jump way up to 11GB while RAM goes to around 5.6GB. I have 16GB of RAM and in an attempt stop the pagefile usage from jumping up so high in Witcher 3 I disabled the paging file that was on my C: SSD. But even with the paging file disabled AB displays 11GB pagefile usage when playing Witcher 3.

Any idea on 1 why my GPU's won't use 99%, and 2 why the pagefile usage jumps up to 11GB? I've included a screenshot of AfterBurner below.

Thanks

 

I was too new to post the screenshot but should have enough posts to post it now:
