 ## Select an appropriate GPU optimized Azure virtual machine size
 
-Select one of Azure's [NV-series](../virtual-machines/nv-series.md), [NVv3-series](../virtual-machines/nvv3-series.md), or [NVv4-series](../virtual-machines/nvv4-series.md) VM sizes. These are tailored for app and desktop virtualization and enable most apps and the Windows user interface to be GPU accelerated. The right choice for your host pool depends on a number of factors, including your particular app workloads, desired quality of user experience, and cost. In general, larger and more capable GPUs offer a better user experience at a given user density, while smaller and fractional-GPU sizes allow more fine-grained control over cost and quality.

 >Azure's NC, NCv2, NCv3, ND, and NDv2 series VMs are generally not appropriate for Azure Virtual Desktop session hosts. These VMs are tailored for specialized, high-performance compute or machine learning tools, such as those built with NVIDIA CUDA. They do not support GPU acceleration for most apps or the Windows user interface.

 To take advantage of the GPU capabilities of Azure N-series VMs in Azure Virtual Desktop, you must install the appropriate graphics drivers. Follow the instructions at [Supported operating systems and drivers](../virtual-machines/sizes-gpu.md#supported-operating-systems-and-drivers) to install drivers. Only drivers distributed by Azure are supported.
 
-* For Azure NV-series or NVv3-series VMs, only NVIDIA GRID drivers, and not NVIDIA CUDA drivers, support GPU acceleration for most apps and the Windows user interface. If you choose to install drivers manually, be sure to install GRID drivers. If you choose to install drivers using the Azure VM extension, GRID drivers will automatically be installed for these VM sizes.

 * For Azure NVv4-series VMs, install the AMD drivers provided by Azure. You may install them automatically using the Azure VM extension, or you may install them manually.
 
 After driver installation, a VM restart is required. Use the verification steps in the above instructions to confirm that graphics drivers were successfully installed.
 
 ## Configure GPU-accelerated app rendering
 
-By default, apps and desktops running in multi-session configurations are rendered with the CPU and do not leverage available GPUs for rendering. Configure Group Policy for the session host to enable GPU-accelerated rendering:
+By default, apps and desktops running on Windows Server are rendered with the CPU and do not leverage available GPUs for rendering. Configure Group Policy for the session host to enable GPU-accelerated rendering:
 
 1. Connect to the desktop of the VM using an account with local administrator privileges.
 2. Open the Start menu and type "gpedit.msc" to open the Group Policy Editor.
