 Swap interval is the interval with which to swap the front and back buffers in sync with vertical blanks (v-blank), the hardware event where the screen image is updated with data from the front buffer. A value of 1 swaps the buffers at every v-blank, a value of 2 swaps the buffers every other v-blank and so on. A value of 0 disables waiting for v-blank before swapping the buffers\*. Setting `swap_interval` is done by sending a message to the system socket: [```swap_interval```](https://www.defold.com/ref/sys/#set_vsync:swap_interval)
 
 ### Caveat
-Currently, Defold queries for monitor refresh rate at init and uses that as a basis for picking a fixed `dt`. If you want to support monitors using variable refresh rate (GSync or FressSync for example) or other scenarios where the refresh rate might not be trivial to query, uncheck `Vsync`to let the engine measure actual `dt` each frame instead of relying on a fixed time step.
