Is it worth is to go from PP11 to PP12 for FBX?

FBX in PP11 is extremely slow and barely usable. I am still using PoserFusion from PP2014. It's got its quirks but I've done great things with it. Since Renderosity has giving up on PoserFusion, using PoserFusion with PP11 is still my best option unless they greatly increased the import export time for FBX.
