I've been doing this setting manually the PreferredBackBuffer when starting the scene
graphics.PreferredBackBufferWidth = 160*GameGlobals.zoom; graphics.PreferredBackBufferHeight = 144* GameGlobals.zoom;
And also when calling the SpriteBatch
spriteBatch.Begin(SpriteSortMode.BackToFront, BlendState.NonPremultiplied, SamplerState.PointClamp, DepthStencilState.Default, RasterizerState.CullNone, null, Matrix.CreateScale(GameGlobals.zoom));
But that gave me issues with displaying sprites at bigger resolutions.
I've tried some things to no avail (like this http://dylanwilson.net/resolution-independence-in-monogame-with-viewport-adapters).
Any easy way to make the screen/viewport bigger? Or maybe I need another thing and this isn't what I'm seeking?
