I have been trying to play the new Modern warfare BR but whenever i try and play my fps keeps dropping and my screen freezes. i have a gtx 1080, an i7 8700k and good cooling and i run at pretty modest settings considering my specs but i still drop so i know its not that my PC cant handle the settings. i have noticed that my memory reaches around 90% and upwards the whole time so i was wondering if that is the issue. i only have 8gb of ram its DDR4 2666 speed but i dont want to buy more unless i have to. I have all up to date drivers. Any help would be much appreciated.
