what is game driver preferences meaning in developer setting?

there is a lot of lagging issue while playing pubg mobile, from drops from 59 fps to 30 fps for some seconds .
some youtube videos and bloggers stating that change the game driver preferences to make fps stable.

Game Driver Preferences allows developers to use custom graphics drivers targeting specific apps. The drivers need to be installed locally and developers have the option of switching between them at will.
Some say enabling one of this options in PUBG will force Vulkan which offers better and more stable performance. I'm not sure and I haven't been able to confirm this myself.
Regardless if it does offer any real improvement (which it clearly doesn't do for everybody), this is not something we will implement because of various reasons.
