OK, so. I've tried to look all over google to find the solution for this annoying problem. In game it's not choppy or skipping frames but when I check out the video it's very laggy and I don't know how to fix it. Yes, I'm recording to another hard drive and I think my PC is good enough to record videos. The problem occurs in every game.

did you ever figure out a solution?
