Severe CPU bottleneck normally implies that your CPU may need to be upgraded though? If you are running a 13900k, there isn't much room for that.

It really just means that that's the component that's limiting performance, not that there's necessarily any way to fix the bottleneck by upgrading.

I can understand bottlenecking the CPU mid game, but doing so on the main menu is a sign something is fundamentally wrong here.
