Scaling my game at a higher resolution appears blurry

The game I'm working on has a screen size of 480x320. Whenever I change the scaling at a higher number than 1x, the images appear blurry in game.  Is there a quick fix to this?

The image on the left is the scene editor zoomed at 300%. The image on the right is the game scaled at 3x.

Go to the game settings and disable all graphics other than 1x

Oh, so it was as simple as that! Thanks a million letmethink!
