No DRX support on T4 instances at Google Cloud

[askqa]

I’d like to know how to enable DRX on T4-based instances on Google cloud.

How do I make a standard Nvidia RTX/DRX tech demo "ElevatorRoom" play? it always says "Nvidia GPU with no DRX support"?

I used "NVIDIA Quadro Virtual Workstation - Windows Server 2019" image from the Marketplace, but I assume T4 does not have DRX support.

Any ideas?

p.s. The ultimate goal here is to have RTX/DRX enabled for Unreal 4.22 engine, but running an Unreal-based demo if just faster.

This is a brief from Nvidia T4 spec sheet:

The Tesla T4 is an RTX-capable GPU, benefiting from all of the enhancements of the RTX platform, including:
• Real-time ray tracing
• Accelerated batch rendering
• AI-enhanced denoising
• Photorealistic design with accurate shadows, reflections, and refractions

What gives?

Make sure you enable GPU acceleration for RDS sessions:

On Windows Server, Remote Desktop Services (RDS) sessions on the RD Session Host server use the Microsoft Basic Render Driver as the default adapter. To use the GPU in RDS sessions on Windows Server 2012, enable the Use the hardware default graphics adapter for all Remote Desktop Services sessions setting in the group policy Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Remote Session Environment.
