Stitching pano frequently hangs with GPU enabled

[Chani Tough]

Using PTGUI 10.0.18.Pro: 1

We have a brand new laptop with a GTX 1080GPU and an i7-8700K CPU.

Whenever we stitch with GPU enabled, the stitching process will hang frequently. It does not crash, it simply freezes and I have to close the batch stitcher and turn off GPU in order for it to complete.

I have the latest NVIDIA driver (clean)  installed (version 397.93). All Windows 10 Pro updates are installed. 

Any ideas what could be causing the GPU to hang my stitching? It does not do it for all panoramas but if I batch it, usually by the third, fourth or fifth one it will have hung (sometimes it goes longer).

Hi Chani,

I'm not sure but I wouldn't be completely surprised if there would be
heat or power issues when using such a GPU in a laptop.

Have you tried stress testing the GPU with other applications?

Thanks for your reply Joost.

The laptop is a workstation that is designed to easily handle intense workloads. We actually have several others that work perfectly. This is the only one giving us a problem so I was trying to see if it was a configuration issue (I did not set this one up but I did set the others up).

Interestingly, I just installed Beta 11 v11 and it appears to be working fine in that version. I don't like using Beta for production work though. Do you know if Beta 11 is stable enough for production work yet?

I am soon off on a 3-week trip where my team and I will be capturing a few thousand pano's so you can see that batching them is imperative.

Hi Chani,

I'm not aware of any major issues in the current beta but I cannot
guarantee that you will not run into any. But then again the same holds
for PTGui 10.

Be aware though that projects created by PTGui 11 are not compatible
with PTGui 10. You can export to PTGui 10 but the panorama would need to
be re-optimized in PTGui 10.

In general projects from PTGui 10 will be rendered identically in PTGui
11, you might consider using just the PTGui 11 batch stitcher. There are
a few specific incompatibilities, mostly limited to mixing landscape and
portrait images in the same project. And the calculation for the optimum
output size has changed but that should not affect batch rendering.

Kind regards,
