Forza Horizon 5 stutters during high-speed driving with Adata Valueram 8GB DDR3 1600, should I use GamePP to clear cache?

While speeding through Mexico, the 8GB capacity of my Adata Valueram DDR3 1600 felt completely inadequate for 4K textures. Memory usage stayed above 92%, forcing the system to lean heavily on the page file, which caused annoying micro-stutters during sharp turns. I was honestly confused why it felt this bad. I first tried clearing temp files, but that did absolutely nothing. Then I opened the GamePP Resource Scheduler Panel and forced Forza Horizon 5 to 'Realtime' priority while capping background services. Checking the GamePP Hardware Sensor Page, I saw the memory controller load stabilize, and frame times dropped from a shaky 16-32ms to a steady 12-18ms.
