Reproduction steps:
1. Observe the attached video “ReproAMD2“

Expected result: Performance is the same
Actual result: FPS degrades when Vsync is enabled

Reproducible with: 2022.3.60f1 (user reported)

Reproducible on:
Windows Standalone Player (observed from the video)

Testing environment: Windows 11 (10.0.26100) (observed from the video)
