Our client is trying to run a 3DF application on NVIDIA L40 graphic card. In this case, 3DF does not recognize L40 and does GDI Rendering. Please tell me how to make it recognize L40.
Hello @mini,
Our suggestion is to check that the proper driver has been installed. If this is not a bare-metail installation and instead a virtualization, the VM machine also needs to be properly configured.
Also, has your client run other applications showing that the GPU and driver are working properly or is the issue just with Visualize 3DF?
Thanks,
Tino
It is not configured as a virtualization server. Another application I checked was Hoops Demo Viewer, which I temporarily installed and checked. It also does not recognize the L40 graphics card, so the graphics acceleration is not working. I will try to find another application and install it, but since the application created with 3DF needs to work, it would be a great help if you could tell me the appropriate graphics driver version or other necessary information.
You can download the drivers directly from the NVIDIA website according to the specific product and OS:
I installed the graphic driver through the official Nvidia website. It is currently CUDA Dirver, but I wonder if I need to take any separate action. And I wonder if the Nvidia L40 Graphic Card is recognized by Hoops Visualize? If you have any reference for this, please let me know.
I’d like to get more information on the GPU by running nvidia-smi. As this requires sharing screenshots, I will connect with you via Jira.
Thanks for sharing the screenshot, @mini.
Based on the results of running nvidia-smi command, it looks like the GPU is in TCC mode which is for compute only. For graphics display, it should be set to WDDM.
Please see the following video for more information on WDDM versus TCC:
Thanks,
Tino

Your support has been a great help.
I solved the problem by changing gpumode to Index 6 using Nvidia mode selector and then changing the graphics card settings using nvidia-smi -dm 0. Thank you.
