Hi,

I’m going to say that at a high level it doesn’t make much of a difference. Some distros will make claims they have tweaks for gaming but for most players I doubt you’ll notice the difference. Almost all distributions make it easy to get Nvidia drivers working these days so I wouldn’t worry about that.

I’d say to pick the distribution based on other factors, such as update policy (rolling vs stable) or desktop environment you prefer.

I wanted to wait to the end to mention Manjaro has some controversial aspects to it. In terms of how the project handles money and leadership. I’d personally not recommend it but that has nothing to do with gaming.
