Currently the objective granularity check is disabled because of the new
mip preprocessor, which is still incomplete. Sorry.
If you know that your objective is integer, you may specify an
appropriate mip gap as Marcelo suggested (say, 0.06 for your example) to
stop the search once the optimum has been found.
A problem with mip gap is that it is fractional.
What does he use if the minimum objective might be -1 or +600?
Using a callback would seem a better option.
