Or that the CPU is not doing needles add servings.

It probably means that there are fewer useless background processes eating up your battery

If you're asking about gaming performance on Linux, then the answer is that it depends on the game. Some run better on Linux (Cyberpunk made headlines recently) and some run worse.

Edit: ah, you're asking any Armory Crate because they have the performance modes. That's just overclocking. You can do that on Linux, but it won't be as easy as using Armory Crate.

No, I have also found that my processes run faster on Linux than on Windows. I don't know what is armoury crate but from the way you're talking about it it manages CPU modes.

Whatever you do in Windows, you can in Linux (almost). But it is sometimes harder, sometimes simpler.
