Build Tiled Model not using GPU - Failed to initialize context.

[MichalDV]

Hi,

I have a rather large project processing, during this step, it seems not using GPU but CPU which makes it super super slow.

Metashape 1.8.1 Build 13915 Windows 64bit

Code: [Select]

Hello MichalDV,

The problem is related to unexpected Vulkan driver update that is not considered by Metashape 1.8.1. We will fix that in the next update of Metashape 1.8.2 pre-release, meanwhile the temporary solution could be either disabling GPU for the texturing (via tweak) or to rolling-back NVIDIA drivers to 497.29 version (Dec 2021).

Thank you, rolling back drivers now.

Hi! Just encountered the same issue with updated NVidia drivers:

I didn't have this problem with 1.8.4 and older drivers. Should I roll back?

Hell ilia,

Have you tried to download and install the most recent NVIDIA driver?

Hi Alexey,

Thank you for the quick reaction.  Updating to the

Driver Version: 516.94

helped me to solve it.
