Im completely new to construct 3 and only basic programming knowledge.I just want to know if viewport size affects the performance of the app on the phone.I I set my viewport to 720 x 1280(9:16 aspect ratio) my full screen mode is set in letterbox scale when I test it on the desktop,FPS runs smoothly about 58-60fps but when I tried it to my phone I got 60fps then sometimes drops to 30-40fps.
