Vivecraft 1.16 and 1.15 are definitely more performant than 1.12. The main changes are in base minecraft java itself (i.e. all the nether changes in 1.16). The main deficit of minecraft 1.16 is mods; most of the big mods only work on 1.12 still, so if you care about that, you're stuck with shit performance but mod support on 1.12, or only a few mods but much better performance on 1.16.
