Wanted to pop a reply on here as it is related to the larger master thread on this issue. This does not solve the problem. What this does, however, is act as a shortcut for disabling Shadowplay which does exacerbate the problem. So if you are among the list where disabling Shadowplay fixes your problems to the point of being able to play the game, that's all this is doing for you. Since NFS (2015) doesn't have a Fullscreen Windowed mode, I would not suggest anybody try and play this game Windowed - that's a horrible experience.
Verified on my system here that running in Windowed mode made no difference (beyond the disabling of Shadowplay), and the problem still occurs.
