I do have a Steelseries Rival but, i have done this test before, on the first day and redone it again and the problem is still there, its a little better with a controller but it doesnt fix the real problem.

For example when i first get in the game, the first menu, I click on Story and let the camera move and I press escape right away, when i look at the background I see the frame skipping/stutters all over the place and im not moving with my controller or with my mouse. The game move the camera by itself, scripted.

Did you try on a different pc ?
I have my old r9 280 graphic card i wanted to try the game with it and see if the prob persist but i am too lazy to change the card and everything.
Have you heard from the developper?
I am convince that this is an issue with their engine.
