Should GraphicsDevice be a global variable?

Hi, I’m just rearranging my game’s code a little bit as it had a lot of dependencies on one class. During this process, I’ve discovered that I was passing in the GraphicsDevice from my game class into almost every other class and realised it might be more efficient to just make it a global static instance.
I’ve heard that global variables are bad practice though so I’m just wondering if this is a good idea.
Thanks,
Seth

My opinion: Yes, no problem for a smaller project to keep a static reference to your ContentManager and GraphicsDeviceManager. My first project did this and it worked just fine. For a larger project consider using dependency injection so you don’t have to worry as much about passing things around.

I even make my game object be a global variable.

Personally, I’m not a fan of Dependency Injection except for some edge cases. I use a Global for my Graphics objects since they are part of the API and used no matter what the platform is.

If I had to use different Graphics objects for different platforms I might consider DI.

Dont really need to. Could use Game.Services.AddService or Game.Services.GetService. Monogame also adds its own services to Game.Services too.

Remember Services are not Monogame Components but you can access them from anywhere if you got Game.*
