I have done a test to make sure this was only in 'Very High Settings.' Whenever I go to the 'Very High' settings option and then hit the escape key, it will freeze the game for 2-5 seconds. I know this sounds like such a tiny problem for a tiny amount of people, but with some further testing, I found that some settings period put on 'Very High.' I believe I have narrowed it down to, Shading, Post Processing, and Object Details set to very high coupled with everything else set to high or medium will cause this. It's not a super big deal because I usually have them set to just High and everything else maxed out so I can get a good looking game with equally good frames. A little tip of advice for anyone doing settings tuning, only the three settings I listed plus V-Sync and resolution make actual frame differences. Reading some other posts, I think 'Very High' settings overall cause some glitches and bugs in the game.
