Built game lags in unity 2019.4.10

Unity Engine

Hi, the game built using 2019.4.10 lags compare to a game built in unity 2018.

The settings should be similar since i am copying the project setting over to the newer version so not sure why the game lags.

Is there some new settings I should configure in unity 2019.4 to fix the lag?

Compare the output of the Profiler between a build in 2018.x and a build in 2019.4.10. Make sure you are comparing build performance and not in editor performance.
