rx580 4 gb vs gtx 1060 3 gb dx11 in Metro Exodus x3440

Hello, in this video we can see test benchmark in a game Metro:Exodus. In the process videomakes i had a problem with connecting video track. Video sequence with GTX 1060 3gb was very slow, which stretched the video and the fps is more smooth. We can find this in video. In the first segment DX11 I connected the beginning and the end, but the middle began to diverge. So, or videodrivers AMD was crude, or Nvidia was bribed the developers of the Metro.
