The week before the update I wasn't having any issues. Since Season of the Lost release, my frame rate has been unstable. My frames drop to 15/20 when they normally should be about 60 fps. I made a hardware change (adding two hard drives) but issues were happening pre/post hardware change. Other than that no other changes to my knowledge. Checking my device manager, my CPU stays under 40% and Ram is around 80% (while streaming video on same system). Let me know what else I can provide to help.
