So this is a strange one to me. My wife has had a massive stutter/frame drop going on whenever she plays...for years. It happens on the minute, every minute, she'll have a drop of anywhere of 20 to 110 FPS (from 120 to 100 or as little as 10). I thought with the cycling it was a RAM issue. And twice now I've upgraded her RAM. And initially, both times I've expanded the RAM, the issue has gone away...for about a week, and then it comes back.

Now to be even weirder, this issue has persisted between two completely different computers. One was a custom built, the new one is 6 months old.

Current Build:
Processor Intel Core i7-10700K 3.80 GHz
Cache Per Processor 16 MB L3 Cache
Memory - Corsair Vengeance RGB Pro SL 32GB (2x16GB) DDR4 3600
Prior memory was G.Skill TridentZ RGB 16 GB DDR4 3200 MHz
Storage 1 TB Intel 660P M.2 NVMe SSD
Graphics ASUS ROG Strix GeForce RTX 3070 O8G (White)

I've tried reinstalling the game, make sure all background apps are off, no 3rd party software running, running memory diagnostics to see if there's a leak and I can never find one. Max RAM useage is like....30% or something, not near 100 at all. I am at a loss.
