 At the same time, Game 60 FPS / Magpie 60 FPS. I find that this situation appears when I am using Magpie v0.10.6. Enable vertical sync in Magpie settings and use "Vertical sync: Use the 3D application setting" for Magpie program settings solved this. Upgrade to Magpie v0.11.1 also solved this.
 
+#### Crazy frame lose when GPU usage nears 100%
+
+At the same time, Game sightly lower than monitor FPS like Game 57 FPS / Monitor 60 Hz. If not use Magpie, the native game window looks smooth.
+
+Try turn off "Hardware-accelerated GPU scheduling" and restart. I find that when GPU under heavy load and GPU scheduling on, Either WGC and Desktop Duplication can't process frames correctly. By turn off GPU scheduling, your game FPS is still low, but Magpie will not drop to visually under 10 FPS anymore.

 #### Screen looks not smooth but FPS is decent
 
 Game 60 FPS / Magpie 60 FPS / Monitor 60 Hz, but some frames dropped after rendered, instead of present on screen. This also happens on native game Window without use scaling.

 * 在 Magpie 设置中启用垂直同步，并在 Nvidia 控制面板中将 Magpie 的垂直同步设置为“使用 3D 应用程序设置”。
 * 升级到 Magpie v0.11.1 也能解决此问题。
 
+#### GPU 使用率接近 100% 时 Magpie 丢帧严重

+同时，游戏帧率略低于显示器帧率，例如游戏帧率 57 FPS / 显示器帧率 60 Hz。如果不使用 Magpie，原生游戏窗口看起来很流畅。
+
+尝试关闭“硬件加速 GPU 计划”并重启。我发现，当 GPU 负载过重且 GPU 计划开启时，WGC 和桌面复制都无法正确处理帧。关闭 GPU 计划后，游戏帧率仍然很低，但 Magpie 不会再“视觉上”低于 10 FPS。

 #### 屏幕观感不流畅，但帧率看起来正常
 
 游戏 60 FPS / Magpie 60 FPS / 显示器 60 Hz，但出现丢帧。这种情况在未缩放、直接运行游戏窗口时也会发生。
