Increase app speed and responsiveness via Screen Scale puzzles?

As I have updated my browser game Megaman X: Nightmare to be playable on mobile browsers from mobile devices like phones or tablets, I noticed that on some mobile devices this game is somewhat slow and laggy.

While I definitely have used Verge3d Optimizing techniques like minimizing vertices and triangle count, using vertex colors and minimizing texture file sizes, and checked for performance bottlenecks (e.g., no shadows, lights), as fundamental verge3d app optimizing –

could set screen scale puzzles and Native screen scale puzzles help optimize user performance

(e.g., by detecting the type of device the browser game is played on, the screen scale puzzle accordingly changes its value so the browser game runs faster and becomes more responsive)
