For what it's worth I just got a new super silent computer with a 5090 and ran into this, the rest of the computer is so silent that when I rotated the viewport I would hear, granted rather low, coil whine from the 5090. But as John suggested, forcing vsync and it was gone. Thanks a lot !

Allright figured out what was causing the issue. Display Options 3D Textures Limit Resolution was unticked which caused the massive RAM usage. Clicking that and it is all good again.

Using Win 11

Installed Linux Mint 22 and tested it out and worked flawlessly so maybe time to reinstall windows. or just upgrade the cpu.
