Hi [TiberiusTyrone](https://forums.unrealengine.com/u/TiberiusTyrone),  
in next release there will be a warning if the GPU is not sufficient to use Version 2 for meshing and it will be set to Version 1.  
Regarding the alignment issue, is that happening for various datasets? Is it happening after application restart ( clear the cache manually as [described here](https://forums.unrealengine.com/t/cache-temp-folder/766674), and launch the application whilst holding down shift, and you should see the following options:

Then select “make like a clean install”)  
Also, your alignment settings are not ideal. Can you try just pre-defined ones?

Version 2 for meshing is much quicker (in some cases 2x quicker, [Introducing RealityCapture 1.3 | Course](https://dev.epicgames.com/community/learning/courses/ev9/capturing-reality-introducing-realitycapture-1-3/mP21/capturing-reality-faster-model-reconstruction-and-texturing)).
