@gkjohnson Updated the post with a screenshot of our game before/after. The example provided is using the exact same logic: // before
vec3 res = ( coord.x < 0.7 ) ? backColor : vec3( 1.0 );
// after
vec3 res = mix( backColor, vec3( 1.0 ), smoothstep( 0.7 - fw.x, 0.7 + fw.x, coord.x)); |

Have you considered halving the fw when using it as a step in the smoothstep function? As it is the step will happen over two pixels which will result in a less crisp edge than it could be:
return mix( vec3( 0.7 ), vec3( 1.0 ), smoothstep( 0.7 - fw.x * 0.5, 0.7 + fw.x * 0.5, coord.x ) );Also nit: can we use 1.0 instead of 1. for consistency and make sure we have consistent spaces inside the parens.

Indeed! Updated the PR with the changes.

Code looks good to me! I trust @RenaudRohlinger has tested it.
