Use the hardware default graphics adapter for all Remote Desktop Services sessions This policy setting enables system administrators to change the graphics rendering for all Remote Desktop Services sessions on a Remote Desktop Session Host (RD Session Host) server. If you enable this policy setting, all Remote Desktop Services sessions on the RD Session Host server use the hardware graphics renderer instead of the Microsoft Basic Render Driver as the default adapter. If you disable or do not configure this policy setting, all Remote Desktop Services sessions on the RD Session Host server use the Microsoft Basic Render Driver as the default adapter. NOTE: The policy setting affects only the default graphics processing unit (GPU) on a computer with more than one GPU installed. All additional GPUs are considered secondary adapters and used as hardware renderers. The GPU configuration of the local session is not affected by this policy setting.
