I have a gtx 1070 and black ops 3 runs at 22-59 fps at 1080p because of the low gpu usage. In other games, its maxed (gta v and fallout 4).CPU usage is around 20-30% as well. How do I fix this? Before you talk about bottlenecking, I have an i7 4790 and 8GB RAM. Is there a way to increase the gpu usage to max in game? (btw drivers are up to date)
