IGT is not so different from real time because I switched from fullscreen mode to windowed mode to check if run is recording. While switching from fullscreen to windowed mode, IGT stops, but real time doesn`t. Also I didnt stop real time in the end of it, so I opened video editor and checked when it should be stopped. This time was 40:15. Anyways, new PB. P.S. I switched to 1.3 and sometimes it is lagging for no reason, and while game lags, video is also lagging.
