Question
Why does the MIKE software not find my GPU card?
Answer
If the GPU is not recognised by the MIKE software, it may be due to the following reasons:
#01 - An outdated GPU driver
An outdated GPU driver does not work with the given version of the MIKE software. Please try updating the driver via the NVIDIA download page
Note: Some tools may falsely report the GPU driver to be the latest. Therefore, always check which driver version is installed using the Windows Device Manager - see example in Fig. 1, where the last 5 digits show the driver version - in this example case 398.36. Compare with the latest driver version provided on the NVIDIA download page.

You may need to select the download type 'Game Ready Driver (GRD)' to get the latest driver
#02 - MIKE software not supporting the GPU
For example, MIKE Powered by DHI release 2023 and 2024 only support NVIDIA GPUs with Compute Capability 6.0 or higher. A list of GPUs and their respective Compute Capability is found on this page Your GPU Compute Capability. As NVIDIA plans to discontinue the support for several generations of GPU cards, we advise all our users to start upgrading to GPU cards to Compute Capability of 6.0 and above.
Note: The expiry date for the GPU option in the license file follows the SMA expiry date.
Conclusion
If the GPU has been successfully recognized by the MIKE software, then the “Parallelization” tab in the “Launch Settings” dialogue in the respective MIKE FM editor will look like example in Fig 2 (left). Otherwise, it will look like example in Fig. 2 (right)

Similarly in MIKE+, the user of GPU will be disabled if the GPU card has not been successfully recognised - see Fig. 3.
