`WinRT.GraphicsCapture` | Yes | Yes | Yes | Yes | Yes | 35 | 36 | - `Games` is checked using [Märchen Forest](https://anemonecoronaria.sakura.ne.jp/merufore/). 37 | 38 | ### Compare with capture

:--------: | 54 | | `Win32.BitBlt` | ~ 20ms | 55 | | `Win32.DesktopDuplication` | N/A | 56 | | `Win32.DwmSharedSurface` | ~ 20ms | 57 | | `Win32.DwmThumbnail` | **0ms** | 58 | | `WinRT.GraphicsCapture` | ~ 40ms | 59 | 60 | - I used [this video](https://www.youtube.com/watch?v=rf2Lmfqi5ZM) to investigate the delay. 61 | - It is just a reference value, but it is certain that the delay of `Win32.DwmThumbnail` is 0 ms. 62 | - This is because it uses a drawing method that is entirely common to other windows. 63 | 64 | ## License 65 | 66 | This project is licensed under the
