Yeah. True. I can sometimes notice the stutter on games like Watch Dogs and Watch Dogs 2, and that is tolerable.
And then, I went into a multiplayer game of BF1.
40 players, so not maxed.
I had a feeling, that it was less than 20 fps. So goddamn laggy.
I asked my friend about it, he owns a PC and a ps4 too, and he said same thing started happening to him approx. 1 year after the purchase.
He fixed it however, by simply, buying an SSD.
Not investing my money, SSDs are not cheap, especially not 1TB versions :/
