Doesn't detect D3D9 Vsync state

PresentMon reports SyncInterval=0 even when Vsync is enabled in the game. Screenshot

Is it possible to provide an ETL (ETW trace log) for reproducing this?

Isn't it by design? For Direct3D9 swap interval is not a Present call parameter, it is Direct3D device's creation parameter. So I supposed it is logical to be unable to see it per each ::Present call in such API environment.

Looks like it only does so if G-Sync is enabled, for both D3D9 and DXGI. Is this how variable refresh rate supposed to work, even when framerate is limited by Vsync? ~Here's the trace: https://drive.google.com/file/d/1x8RVnhbdZ-p33Z-0jmMNa2Uuldc-Pt7M~
