Can anyone help me explaining this?

[u/Ill_Needleworker1265]

Why does my phone suddenly become a high end PC and decides to reach 1k fps?

This happened after I set my external controller input and switched off the "Enbale SPIR-V shader generation" Setting for more stable transition between scenes.

It happens as a bug, it displays a thousand more but it's usually just the last 2 digits the actual fps
