Dear Sir/Madam,

We are using CST on a computer with Nvidia RTX A4000 GPU with a GPU token, which supports CST Studio Suite  time domain solver. But after a recent update on the NVIDIA driver (it was updated as CST was asking for it), I have noticed the following message, as attached in the picture:

 'Hardware Accelerator Device info:
    - CUDA_MODULE_LOADING is set to: LAZY'.

This has significantly slowed down the GPU computation process compared to before the update. 

However, I tried setting CUDA_MODULE_LOADING=DEFAULT  in the Windows 11 environment variable. But the problem still persists. CST still shows: 'Hardware Accelerator Device info:- CUDA_MODULE_LOADING is set to: LAZY'. It is slower compared to before. Any further help is solicited. The GPU configuration is attached here.

Please help us get back to faster CST computation.

With thanks and regards

Saurav
