The title says it all, all i can get is 45 fps in certain areas, huge fps drops, continuous 100% CPU usage, around 10% GPU usage and, as task manager says, a very high power usage and power usage trend caused by GTA5.exe. I have an Asus 1080ti Turbo and a Msi Z490 Gaming Plus mobo. I really could use some help, I don't know if this is normal but it doesn't seem to be.
