How to enable GPU utilization for Topaz Gigapixel AI on an Azure VM?

Question

I am running Topaz Labs Gigapixel AI on an Azure virtual machine (VM) with the following setup:

• OS: Windows Server 2019 Datacenter (Version 10.0.17763)
• CPU: Intel or AMD with AVX instructions (post-2013)
• RAM: 16GB
• GPU: NVIDIA Tesla T4
• Driver Version: 529.19
• CUDA Version: 12.5
• Gigapixel AI Version: 7.0

Despite configuring GPU settings and ensuring drivers are installed, Gigapixel AI only utilizes the CPU, and the GPU remains idle. nvidia-smi shows no processes using the GPU.

Steps Taken:

1. Installed NVIDIA driver and CUDA 12.5, verified with deviceQuery and bandwidthTest utilities.
2. Enabled GPU settings in Group Policy.
3. Ensured Gigapixel AI is not in compatibility mode for Windows 8.
4. Verified GPU passthrough to the VM.

Request: I need help enabling GPU utilization for Gigapixel AI on this setup. Any specific configurations or troubleshooting steps?
