Switching from Windows to Linux, how different is the performance?

I've been a Windows user for my entire life and these last few years I have not been enjoying using Windows so I started using Ubuntu in a VM (I chose Ubuntu because it was my first time using Linux and I was more familiar with it) and I liked it so much that I'm thinking about using it as my main OS.

Now the question is, how much will my performance be affected by this change? I was thinking about using Fedora with a virtual machine that has a Windows machine, or just using Pop OS for gaming since I can use Gnome with both of them. Are these good ideas? If not, then what would be some good options for sacrificing the least performance in comparison to Windows?
