Why some games need to be restarted when we change the resolution or graphics settings while others manage do it on the go?
In: Technology
When changing some settings, it’s just easier to reset all the variables to their starting values rather than trying to account for all the changes that would need to be made to allow the setting to be changed on the fly.
For instance, maybe the game calculates physics based on screen resolution. Changing the resolution means lots of variables that were previously set need to be recalculated. This can become a nightmare for testing, and lead to very subtle bugs. So the easy way out is to just apply the setting after the game is restarted.
