Constant idle CPU usage with IE11 on windows 8.1 (64-bit)

I'm not sure but I think all this started about 7-10 days ago, maybe more.

I disabled pretty much every add-on that I could. I also disabled IE's built-in ad blocking TPL lists. None helped; in fact, and this is very strange, disabling flash actually causes CPU usage to go UP.

Also, if I let the page sit there for a while, it tends to cause IE to reload the page with a message "something went wrong, etc. please reload". Can't remember the exact message.

Here is a video I recorded. The first site is for reference, and as you can see, 0-1% usage (This is true for all the websites that I regularly visit). Then I open gamespot and it idles around 8-12%. This is with flash enabled.

I also generated a UI responsiveness report with IE's F12 tool.
