Some times I've had longuish freezes. They've happened only while running either OBS or Radeon Relive. I have the suspicion there may be something with the game, perhaps the NGS? (I hope not, but considering OBS can choose to pick the image from an app and ignore other windows on top, which I use, got the idea) that may have some kind of clash with screen recording software and some times cause the freezes. They're rare, not frequent, but happen.
