High input lag when game is built

Unity Engine

During the development process I obviously ran my game in the editor many times without any input lag. However, when I build my project, there is a significant input lag despite there being a high frame rate.

Here are my specifications:
Version: Unity 2019.4.15f1 Personal
OS: Mac OS Catalina v10.15.6

I have already tried searching for solutions but all related threads do not have any helpful answers.

I fixed the issue.
Instead of selecting File → Build And Run, Select File → Build Settings → Quality and turn VSync off.

Exactly my issue. Thanks for updating your own thread!
