rtx 2080 super modern warfare 4k

Hey fellas. I have an RTX 2080 super with ryzen 7 3800x and 16GB ram. I want to know what settings to use in modern warfare to get steady 60 fps in 4k. Is there an app that I can download to say "I want 60 fps" and the software automatically adjusts the graphic settings? I have disabled ray tracing but left everything on but occassionally get below 50 and this is unacceptible in multiplayer. Thanks in advance folks.
