RDR2 keeps stuttering in big towns on my MSI PRO B760M-A due to memory overflow, can priority settings help?

Trying to run 4K textures on DDR4 in this open world is a joke; every time I hit a town, the system just chokes on the page file. RAM usage was pinned at 92-96%, and my frame times were jumping randomly from 18ms to 140ms—it was absolutely unplayable. I tried closing every single background app, but even with just a browser open, the memory was maxed out, which felt pretty hopeless. I ended up manually setting the virtual memory to 64GB on my PCIe 4.0 NVMe drive and set the game process priority to 'High' in Task Manager. While the page file read/write is still heavy in the performance monitor, the second-long freezes have finally stopped. I noticed my boot time slowed down by about 8 seconds after the change, but disabling Core Isolation brought it back to normal. RAM temps are now 45-51℃ and the SSD is at 58-64℃. I exported the memory swap curves to verify the fix, with fans steady at 1400-1600 RPM.
