Same problem was here. When I use the Kaspersky my fps is less, and when I play with Cold War i have the big fps drop. Uninstall Kaspersky, downloading again the shaders in game= problem solved. Kaspersky is best protection, but not good for operating system and not good for gaming yet. Too many drivers use, sits on the system, and etc, and Kaspersky have too many unnecessary protection component. I love the Russian product, but the road is not good what they are going for.
