This happens every 10-20 minutes and doesn't seem to impact performance because right after my card goes right back to pushing 165+ frames.
Specs:
AMD Ryzen 7 5800X3D
MSI SUPRIM X RTX 3070
32GB Corsair Vengeance 3400 MHz DDR4 Memory
Asus ROG STRIX B550-F gaming motherboard
Windows 11 latest update
Haven't gotten footage of it happening, and I've already run Aida 64 bit to see if my GPU is thermal throttling (it's not). I do think it may have something to do with the fact that my GPU is vertically mounted but it showed no signs of a performance hit 2-3 months after having it in vertically
I'm not sure if this is a hardware related issue. Or a software related issue.
