Laptop (no tearing on non vrr display?)

[nekkzu]

Hello guys.
I am a proud owner of new MSI Cyborg 14 (switched from beefy desktop).

My new finding after a week of use is -- somehow there is no tearing on this laptop .
Panel NE140WUM-NX1.
No MUX switch, VRR(Adaptive Sync & G-Sync) is not supported; Intel Arc Control display - VRR not supported, G-Sync not present.
But somehow I get zero tearing in games/tested with Pendulum demo.
Intel Smooth Sync is not Enabled/No force Vsync in Nvidia.
Do you have any ideas HOW is this possible?
Thanks
