GPU processing failed

[Ant]

Hi there,

I'm using PhotoScan version 1.0.4 build 1847 (64bit) on a Windows 7 Enterprise with Intel Core i7-4790 CPU @3.6 GHz 16GB RAM.

The PC has a GeForce GTX 750.

During the step build dense cloud, the consol says that GPU processing failed and the processing is very slow.

Any advices?

Regards,
Ant

Hello Ant,

You may need to install the latest NVIDIA drivers.

And probably to use PhotoScan version 1.4.2. The version that you are using has been release about four years ago, so there could be bugs that were already fixed since long ago.

Hi Alexey,
Thanks for quick reply!
My NVIDIA drivers are up-to-date.
I've updated to PhotoScan 1.4.2 and it works. Unfortunately I still need to make the version 1.0.4 working as I need to finish a research project that I've already started and for which I need to keep on using the same version for consistency.
I'll try version 1.0.4 on a different PC.
Regards,
Ant

Hello Ant,

Unfortunately, we cannot release the fix for the older version, but I can suggest then to try some older drivers instead of the newest ones.
Maybe you can also provide the processing log from the old version, just for case there's anything obvious that can be easily avoided.
