Stutter/Jitter rtx 2070 metro exodus solution

[LeeroyPCtips]

Hi everyone! I've been having issues with Asus dual rtx 2070 card. I possibly have found a solution, but am looking for confirmation. The pc also has a liquid cooled (with corsair h60) i7-9700k, 16gb 2133 ram, rog strix z370-i mb, M.2 ssd, 600w psu. Nothing overclocked, xmp turned on. So when I play metro exodus the stuttering and jittering is non stop with anything below extreme but frame rates are really good. I have found that if I set my settings to extreme with shader rate at 4.0 it stops but frame rate is awful (as expected). Then when the whole pc warms up and graphics cards warms up I can turn down the settings to recommended and the game runs smooth as silk. So this is more of a suggestion for anyone having these same issues and wondering if this works for anyone else or if there is some explanation as to why this works.
