Heavy Stuttering in Games on High End PC After Latest Patch

Yes, it's another one of these posts.

I'm running a Ryzen 7, 9800X3D with a 5070Ti (16GB VRAM). (Windows 11 with latest update + latest Nvidia Drivers)

Every other game I run (Baldur's Gate 3, Doom: The Dark Ages, Battlefield 6) works smoothly except for League.

And we're not talking random micro stutters, I'm getting a metric fuck-ton of stutters at random points in the game, making it nearly unplayable.

Judging from the recent volume of posts - this seems to be an issue with the latest patch, though we haven't heard any official acknowledgement from Riot yet.
