From what I have heard rust kinda just runs like garbage in general kinda like pubg. My guess is it would be the CPU that is causing the performance issues but I am unsure how much of a difference it would make to upgrade it. Honestly I would look up more about what hardware plays nice with rust or if any hardware can run it well. No point in upgrading if you have no idea if it will make a difference.
