Hi, I think there is still a memory bug that has not been fixed but not released yet see here <https://github.com/RTKConsortium/RTK/issues/612>. Iterative reconstruction techniques currently load the whole volume and projections in memory so the limit is how much you can fit in GPU memory + intermediate volumes. Simon
