Magpie provides several capture modes. They have their pros and cons in different scenarios.

Graphics Capture Desktop Duplication GDI DwmSharedSurface
System requirement Win10 v1903 Win10 v2004 None None
CPU utilization High Low Low Low
Supports DirectComposition (e.g. UWP) Yes Yes No No
Supports recording/streaming No under extreme conditions[1] No Yes Yes
Support the source window to span multiple screens No under extreme conditions[1] No Yes Yes
Ignores DPI virtualization[2] No No Yes Yes
Notes Recommended for 3D games Suitable for games with more static frames[3], could capture pop-ups Low VRAM usage

[1]: (1) The source window does not support the common Graphics Capture (2) The system is Win10 v2004 or later

[2]: The system will perform bicubic interpolation upscaling to windows that do not support DPI scaling. The capture modes supporting this options captures the images before such scaling.

[3]: The Desktop Duplication mode effectively reduces the power consumption if there are many static frames.
