Do the Krea2 INT8 models require some special nodes to work properly? Because on Comfycloud int8 models take double the time that of regular raw/turbo models to gen for some reason

I'm very very confused. Everyone praises INT8 for being faster than fp8, but when I use it on Krea on 4 pics it takes 96 seconds and without it it takes 46 seconds. Am I missing some node or Comfycloud are just lazy to update their platform to support those models? I assume minimax has the same issue, tho I haven't compared them yet
