Can a bad Motherboard cause erratic frametimes?

Hi

I know this is an old thread, but it's super difficult to find threads like these where someone has had this issue. I've also tested multiple parts on my pc, ( gpus, psus, ssd, ram, etc), and get these weird frametime spikes.. I read what the person said above about it possibly being CPU , my msi afterburner graphs look similiar to that. I am running an 8700k , 2070 super, evga 750w, 32gb 3600mhz ram.

 

In COD, it runs pretty smooth. No frametime spikes, or not nearly as bad. In a game such as fortnite, where a potato can run it, I get these terrible 50-100 ms spikes, same as PUBG.

If a grenade goes off, or at times where I fire a weapon, a massive spike will occur. Which makes me believe something is taking up time to process it which leads to stutters. 

I was wondering if you were able to fix your issue from getting a new CPU? Or if you did, what did you do to fix it?

Thanks! 

Hey, I have the exact same problem with my RTX 3080, and intel i9 10900k. Did you ever find out what the issue was?
