Trying to go through the initial processing step with my project and looks like during the ‘Computing Keypoints’ step, it seems as though its just “hanging” at a certain point. I tried splitting the images, meaning just processing half of the total images taken of the project and it still hangs during computing keypoints.  Any suggestions with this? I looked at the log of the project I started yesterday, came in this morning and it was hanging on computing keypoints. You can see the log where I killed the program so I can restart and the time between was more than 12 hours. Let me know where I can send the log file.  Thank you for your help and time. ---

Hi Nes, I’ll follow up with you in the ticket which you sent to the Technical Support Team. I’ll post here a solution as soon as we discover the cause. Best ---

Hi. Is there any update to this? I have been having the same issue. Usually force stopping Pix4D and starting again helps, but on my current project I can’t get past computing keypoints no matter what I try. ---

Hi Willem, First, ensure that your graphics card is updated. If you have NVIDIA GPU, please download the newest driver from the [NVIDIA website](https://www.nvidia.com/Download/index.aspx?lang=en-us). Reprocess the project. If it doesn’t work, disable your CUDA capable device in the _Resources and Notification_ tab in the _Processing Options_ window. Reprocess again. Let me know how it works. Best ---

Thanks for they reply. If I update my NVIDIA driver I end up with a whole new array of PC issues unfortunately. I tried disabling the GPU, which stopped the issue of Pix4D hanging while processing, however it ended up corrupting abut 10% of my photos during initial processing . Fortunately I had the original images backed up, so was able to start over, but again I ended up with corrupted photos on the second attempt as well… I then went back to enabling the GPU and processed again, this time it all worked. I’m guessing it must be an NVIDIA driver issue. Thanks ---

Hi Willem, Thank you for the updates.  It is not expected to have any issues after updating the NVIDIA driver. If still, you are experiencing some problems with it I would advise you to check the system or even contact NVIDIA Support. Regarding the processing in Pix4Dmapper and NVIDIA compatibility; we have noticed that this issue is pretty random. From our end, it was even hard to reproduce all the cases. However, soon our team is going to release a new version which includes the fix for that software hang/freeze. I would advise you to follow [Pix4D Desktop preview and technical release notes](https://support.pix4d.com/hc/en-us/articles/115005738363-Pix4D-Desktop-preview-and-technical-release-notes). Within one month, the new version should be ready to download.  Best!
