使用H264的硬件编码似乎性能较差

嗨，
我在Windows 10 1709 VM上安装了XD 7.15 VDA。
这个VM分配了一个GRID P6 GPU（P6-2Q），安装了6.1 GRID驱动程序集，作为7.15 VDA安装的一部分，我选择了HDX 3DPro选项。
我已将超高清用户体验模板应用于我的VM，我在其自己的交付组中作为单个虚拟机进行访问。
当我使用两个4K面板和基于Linux的接收器（13.9.1.6）连接到此VM时，我可以看到H.264编码正在主机端执行（使用'nvidia-smi encodersessions'并通过RDAnalyzer工具 - '
硬件编码=启用'）。
视觉质量为“高”，最大帧数p / s值为60.通过VLC或MPC的视频性能良好，4K播放速度约为25fps（虽然4K YouTube很差 - 我猜测到的编码是不同的
协议？）。
Thinwire是显示模式，为整个屏幕启用了视频编解码器使用。
传输协议是TCP
鼠标性能很差 - 对于我和使用4K面板的Citrix而言，这是一个长期存在的问题，光标位置滞后。
但是，整体表现还是不错的。
然后我打开无损开关激活无损，鼠标性能很棒 - 非常流畅和流畅。
RDAnalyzer报告“视频编解码器未使用”，H.264编解码器流不再适用于主机端GPU。
RDAnalyzer还将Adaptive Display显示为“True”。
当然，现在使用本地视频和YouTube等视频表现都很差。
那么有谁知道为什么我无法获得支持GPU的VM的性能以及非GPU启用的VM的一般感觉和鼠标性能？
这是我缺少或不知道的协议限制吗？
谢谢

Hi,

I've installed XD 7.15 VDA on a Windows 10 1709 VM.  This VM had a GRID P6 GPU assigned to it (P6-2Q), the 6.1 GRID driver set installed and as part of the 7.15 VDA install, I chose the HDX 3DPro option. I have applied the Very High Definition User Experience template to my VM which I access as a single virtual machine in its own Delivery Group.   When I connect to this VM using two 4K panels and the Linux based Receiver (13.9.1.6) I can see the H.264 encoding is being performed at the host end (using 'nvidia-smi encodersessions' and via the RDAnalyzer tool - 'Hardware Encode = Enabled').  Visual quality is 'High' and the Max Frames p/s value is 60.  Video performance via VLC or MPC is good, with 4K playing at around 25fps (although 4K YouTube is poor - I guess down to the encoding being done is a different protocol?).  Thinwire is the display mode, with Video codec usage enabled for the entire screen.  Transport protocol is TCP

Mouse performance is poor - a perennial issue for me and Citrix using 4K panels, with a lag behind cursor position.  However, performance overall is good.  Then i turn on the lossless switch to activate lossless and mouse performance is great - really fluid and smooth.   The RDAnalyzer reports 'Video codec not in use' and the H.264 codec stream no longer applies on the host end GPU.  RDAnalyzer also shows Adaptive Display as 'True'.  Of course, now video performance is poor using both local video and YouTube, etc.

So does anyone know why I can't get the performance of a GPU enabled VM along with the general feel and mouse performance of the non-GPU enabled VM?  Is this a protocol limitation I am missing or unaware of?

Thanks
