What's the solution here? I'm using Windows 7. If the VSync rate is 60 hertz (Hz), the VSync interrupt occurs one time In this circumstance, the DWM gives control of the display and almost all the CPU/GPU power to the game. Click or the topic to expand the content:. In this case I consider it likely Windows 11 improves on this behavior by making borderless apps running at the exact desktop resolution skip the DWM entirely, but if you're running in a smaller window or an earlier version of Windows this will not take place, which The game forces vsync now this can cause some serious microstuttering on some configurations. " How come Windows can run triple buffering in windowed mode while Vsync is disabled?
