Low FPS/Game freezing up suddenly

[Frogmaster33]

I never had performance issues before but now I can't play smoothly anymore as of recently. I get low FPS drops and the game is just freezing up suddenly. It doesn't look like it's my internet. Is the game no longer optimized as well or is my pc just getting outdated?

When I played Rust recently, my task manager was showing around 22GB of memory space being used with Rust alone. Your processor, storage, and graphics processing unit meets the recommended specs, but the memory does not now. NOTE: This is my experience with Rust and the ram usage. I suggest getting 32G, just to be safe. I am guessing that your operating system has resorted to using the swap file due to running out of memory space. (Theory)
