Unfortunately, this was a limitation of WGC, especially on older versions of Windows. Recent Windows 11 builds should not have this behavior and should do a better job only updating when there are changes to the window. What version of Windows do you see this on?

I had observed this in all versions of Windows, starting with the first version that supported it for classic applications Windows 10 1903 and ending with the current installed Windows 11 22H2. I haven't noticed any change in API behavior between all the intermediate releases. Now, when capturing a game locked at 30 FPS, API sends about 140 frames a second (floating) when on 144 Hz monitor. If it should improve, what could I be doing wrong?
