Taking time for polished new version ie 4.7 is highly lauded! Previously, my instinct regarding (after reading threads of not working features after upgrading - and then, not fixed in the minor version kinda freaked me out) Unreal is to stick to version which is deemed as stable and therefore, forgo any nice update like FPS improvement, new features. Which is quite bad actually, but necessary as features which used to work and not working after upgrade is technical headache to me, to say the least.
