Many modern games have multiple settings to change to allow for lower end devices to run the game, and higher end devices to see a better looking environment. So, with this, my question is what kind of performance impacts would it have to create this sort of optional looks where textures, particles, etc., of difference resolutions would be loaded in and then the player would choose which they would prefer.
I know it usually creates a bigger file size in games, so loading times would be impacted, but since they have to choose between one or the other, and one isn’t being rendered on their device, would the other choice still impact performance while playing the game? The only application for options like this that I’ve seen usually just enable/disable content such as dust or leaves, rather than lowering resolution.
