Question Need Help with Random Frametime Spikes in Many Games

[endurancist]

I'm having random frametime spike issue with a lot of games. Not all of my games have this issue but most like Overwatch, Dota 2, Rise of the Tomb Raider etc. I included the MSI Afterburner monitor log for Overwatch below because I think Overwatch is generally well optimized. Here are the files, the frametime spikes in the graph go to around 70ms to 80ms. I also use the framerate limit function built-in with RivaTuner Statistics Server since it produces the most consistent frame rate. Any help is appreciated!

CPU: i5 9600K
GPU: RTX 2060 FE
MOBO: ASRock Z390 Phantom Gaming ITX
PSU: Corsair SF600
RAM: Corsair Vengeance LPX 3200

Temps are CPU around 50-60, GPU around 70.

The short periods of zero frame time in the graph is when I switched out of the game back to windows. Everywhere else is within the game.
