是否有其他人遇到表面pro 3 + kinect v2的问题？ [英] Is anyone else having trouble with surface pro 3 + kinect v2?

问题描述

我在Surface pro 3上安装了cpu密集型Kinect v2 程序（已安装所有更新）。当cpu频率为100％时，它通常会消耗大约50％的处理（所有CPU和网络，没有图形）

I'm running a cpu intensive Kinect v2 program on a surface pro 3 (all updates installed). It typically consumes about 50% of the processing when the cpu frequency is 100% (all CPU and networking, no graphics)

问题是有时当 我运行程序cpu频率（由资源监视器报告）不会从它的空闲状态33％移动，所以我的程序窒息。如果我拔下电源线，cpu频率会立即跳到100％。如果
我然后更换电源线，cpu频率将保持在100％。我的程序将保持运行状态一段时间，然后频率将再次降低 - 我可以通过移除或更换电源线来修复它。

The problem is that sometimes when  I run the program the cpu frequency (as reported by the resource monitor) does not move from it's idle state of 33% so my program chokes. If I remove the power cable, the cpu frequency immediately jumps to 100%. If I then replace the power cable the cpu frequency will stay at 100%. My program will keep on running fine for a while and then the frequency will drop low again - I can then repair it by removing or replacing the power cable.

显然这个程序是密集的，粉丝会打开冷却的东西，所以我原本以为这是一个过热的问题，但问题可能会立即发生在运行程序时，表面刚刚启动并且完全是
冷，或者当它很热时不会发生。我已经尝试过电源选项（表面上并不多）但它们没有明显的效果。

Obviously this program is intensive and the fans turn on to cool things down, so I originally thought it was a overheating problem, but the problem can occur immediately on running the program when the surface has just been booted and is completely cold, or not occur when it's hot. I've tried the power options (not many on the surface) and they have no noticeable effect.

有没有人有任何建议？我如何从CPU获得最大性能并保持在那里？为什么电源线会产生这样的效果？

Does anyone have any suggestions as to how I can get the max performance from the cpu and keep it there? Why should the power cable have such an effect?

谢谢

推荐答案

您运行的是WPF应用程序还是c ++应用程序？尝试同时运行任何D2D示例，以查看是否更改了行为。当你启动时，机器当时是否已通电？根据电池和插入电源的运行情况，有不同的硬件状态
a系统。系统是否在插入电池时为电池充电？

Are you running a WPF application or a c++ application? Try running any of the D2D samples at the same time, to see if that changes the behavior. When you boot the machine was power connected at the time? There are different hardware states a system can be in based on running on battery vs plugged in. Is the system charging the battery at the time it is plugged in?

如果使用电池假设你需要保存哪些操作系统/硬件将以节能状态运行，直到它被强制运行100％（游戏或其他图形密集型工作）。 CPU绑定操作可能不会触发
升级到全速，具体取决于操作系统处理特定进程的方式。由于业务线应用程序通常不会经常更改屏幕，因此WPF的性质旨在更新频率更低，因此设计为
以更高效的方式。无论如何，D2D / D3D应用程序全速运行。

If on battery the assumption is you need to conserve which the operating system/hardware will operating in an energy efficient state until which time it is forces to run 100%(games or other graphic intensive work). CPU bound operations only may not trigger the step up to full speed depending on how the operating system is handling the specific processes. The nature of WPF it was designed to update less often since line of business applications typically don't change the screen that often, so it was designed to be more efficient that way. Where D2D/D3D applications run at full speed no matter what.
