Does upgrading from 8GB to 16GB fix stuttering in open-world games like GTA V and RDR2?

Yes, upgrading to 16GB will reduce stuttering by a lot. Open-world games are memory hogs, and with 8GB your system swaps to disk when Windows and a browser are open, causing hitches. 16GB gives the game room to breathe and is the sweet spot for smooth gaming in 2025.
