使用8Q vGPU遇到了扩展问题

你好
在使用vGPU时，我似乎遇到了某种扩展问题。
此问题仅发生在新构建的XenApp VM上，所有现有的XenApp VM都可以。
如果我使用XenDesktop，则没有问题，这纯粹是XenApp / Windows Server问题。
我正在使用ESXi 6.0 U2，XenApp / XenDesktop 7.9，Windows 2012 R2服务器，我已经尝试完全打补丁或全新，没有来自.iso的任何更新。
GPU是M60，我使用8GB配置文件。
大量的CPU和RAM，资源不是问题。
对于我的所有虚拟机，我的GRID驱动程序为362.56。
应用程序是多种多样的，随机的NVIDIA演示类型，Redway，你可以下载和玩的通用3D东西。
在这个阶段，应用程序并不重要，因为问题不在于它们。
应用程序的性能很好。
但是看看应用程序/桌面的视觉体验会降低，就好像服务器没有看到GPU，但我使用的SMI和每个监控工具都告诉我GPU正在被使用。
应用程序FPS支持此功能。
这是我到目前为止所尝试的内容：
-  GPU已获得适当许可，我已检查许可证服务器以确保正在检出许可证。
我也尝试重新启动许可证服务器（以防万一）。
- 应用GPO告诉XenApp服务器“使用硬件默认图形适配器......”，我已经通过注册表确保它正常工作。
- 我尝试重新安装NVIDIA驱动程序然后推出新图像。
驱动程序安装的事实，告诉我VM可以看到GPU。
- 我尝试构建一个没有Windows更新的全新虚拟机。
我也尝试了所有当前的Windows更新。
- 我尝试过没有应用GPO或Citrix策略，但它只使用与其他VM使用的策略相同的策略。
- 我重新启动了物理主机。
- 我尝试禁用VMware SVGA 3D适配器，以便只有NVIDIA适配器存在且处于活动状态。
-  NVIDIA SMI显示GPU已分配给正确的VM并且正在使用GPU。
-  DXDIAG表示正在使用Citrix显示驱动程序，Direct 3D加速已“启用”，并且“没有发现任何问题”。
- 打开已发布的应用程序或登录服务器桌面时，解决方案完全错误的事实也证实了这个问题，它看起来像是缩放并运行较低的分辨率。
- 直接RDP没有相同的桌面和图标缩放问题，但我可以说，当我在应用程序中查看正在使用的字体时，它是不对的。
我上传了一些截图。
天堂的运行速度为1024x768（虽然看图像，但你永远不会这么想）。
“桌面分辨率”截图来自我的MacBook Pro，当连接到ICA资源时，它运行1920x1200分辨率，“SMI”显示正在使用GPU。
附加的“RDP GPU.jpg”显示2x RDP连接。
左侧的服务器没有遇到扩展问题，右侧的服务器遇到问题。
我可以通过查看打开的监视器上的字体大小来看到这一点。
尽管桌面分辨率和图标大小相同，但右侧的那个大于左侧的那个。
我知道当我通过ICA访问它时，整个桌面将被缩放。
我希望这是有道理的。
如果没有，请告诉我，我会添加更多内容。
如果有人有任何建议，这将是伟大的。
谢谢

Hi

I seem to be having some sort of scaling issue when using a vGPU. This issue only happens on newly built XenApp VMs, all existing XenApp VMs are fine. If I use XenDesktop, there are no issues, this is purely a XenApp / Windows Server issue.

I'm using ESXi 6.0 U2, XenApp / XenDesktop 7.9, Windows 2012 R2 servers and I've tried either fully patched or brand new without any updates from an .iso. GPUs are M60 and I'm using 8GB profiles. Lots of CPU and RAM, resources are not the issue.

My GRID drivers are 362.56 for all my VMs.

Applications are varied, random NVIDIA demo type, Redway, generic 3D stuff you can just download and play with. At this stage, the applications are not important, because the issue isn't with them.

Performance of the application is fine. But looking at the applications / desktop the visual experience is degraded, it's as if the server isn't seeing the GPU, but SMI and every monitoring tool I use is telling me the GPU is being used. Application FPS supports this.

Here’s what I’ve tried so far:

-   The GPU is properly licensed and I’ve checked the license server to ensure a license is being checked out. I’ve also tried restarting the license server (just in case).
-   The GPO to tell a XenApp server to “Use the hardware default graphics adapter….” is applied and I’ve been through the registry to ensure it is working.
-   I’ve tried reinstalling the NVIDIA drivers then pushing out the new image. The fact that the drivers install at all, tell me the VM can see the GPU.
-   I’ve tried building a brand new VM with no Windows Updates. I’ve also tried all current Windows updates.
-   I’ve tried with no GPOs or Citrix Policies applied, but it’s only using the same Policies that other VMs are using.
-   I’ve rebooted the physical host.
-   I’ve tried disabling the VMware SVGA 3D adapter so that only the NVIDIA adapter is present and active.
-   NVIDIA SMI shows that the GPU is assigned to the correct VM and the GPU is being used.
-   DXDIAG says that the Citrix Display Driver is being used, Direct 3D Acceleration is “Enabled” and that there are “no problems found”.
-   The issue is also validated by the fact that the resolution is completely wrong when opening a published application or logging onto the servers desktop, it looks like it’s scaled and running a lower resolution.
-   Direct RDP does not have the same desktop and icon scaling issues, but I can tell it isn't right when I look within an application at the fonts being used.

I’ve uploaded a few screenshots. Heaven is running at 1024x768 (although looking at the image, you’d never think that). The “Desktop Resolution” screenshots were taken from my MacBook Pro, which runs a 1920x1200 resolution when connecting to ICA resources and “SMI” shows that the GPU is being used.

The attached "RDP GPU.jpg" shows 2x RDP connections. The server on the left, is not experiencing the scaling issue, the server on the right is experiencing the issue. I can see this by looking at the font size on the monitor that is open. The one on the right is bigger than the one on the left, despite the desktop resolutions and icons being the same size. I know that when I access this through ICA, the whole desktop will be scaled.

I hope that makes sense. If it doesn't, let me know and I'll add some more content.

If anyone has any suggestions, that would be great.

Thanks

Ben
