Dear support,
I would respectfully suggest that you prepare a small document explaining the main tweaks and their use....
They seem to be very useful but seem to be a mystery that is uncovered little by little....
A list of most useful tweak with their effect would greatly help!
More importantly it would be great to not introduce under-the-hood & undocumented optimizations that either make things slower to process compared to the previous version or break things appart with no tangible advantages. This has been the case for a while now.
Performance optimization where done to camera alignment when using Generic Pre-selection: it's faster which is great but a lot less reliable than before which results in the need to align with pre-selection disabled more often thus rendering this feature optimization somewhat moot if said feature can't be used with confidence anymore.
Depth Maps generation has been changed under the hood between 1.5.0 & 1.5.1 (to improve the Dense Cloud quality) which makes it 30% slower on average with no particular benefits when using the new depth maps meshing workflow (there's an undocumented tweak to revert to the old method -> "method main/depth_build_lod - FALSE") which was useful up until 1.5.2 was released.
And now two new Depth Maps optimization have been introduced in 1.5.2 which makes things even worse: it's slightly slower (you have to set "main/depth_build_lod -TRUE" or things will be even worst now) and the meshes generated are simply messed up in terms of topology with holes and unwanted polys all over the place.
For those using Metashape and generating meshes using the Depth Maps workflow sticking to 1.5.1 is IMO the best solution for now.
