We have noticed a problem with recent NVIDIA driver versions, which causes the GPU to stop working in Mocha for tracking and remove.
The problem started with GeForce driver version 416.81 and Quadro driver version 416.78, on Windows 10. With these or newer drivers, the NVIDIA GPU will not appear in the list of available GPUs in Mocha preferences, so tracking and remove will use the CPU or a different, non-NVIDIA GPU if the system has one.
We are in contact with NVIDIA about the problem and will post an update when we have any news on a fix from either our or their side. In the meantime, please do not update your drivers beyond the following versions:
If you have already upgraded, previous driver versions are available from the NVIDIA Advanced Driver Search page.
