You can press F5 and turn down post processing weight in scenes with lots of characters, disable the fires and those effects, if that's still too laggy then disable shadows while posing or turn down far-clipping distance if it is an HQ map.
And your HS2 workspace should be sorted in folders (right), it'll make it easier to disable multiple things at once with one click, especially effects.
If you have SSS enabled, then disable that too.
If there are multiple female characters, check if you're using the DefaultBodyF and not the HighPoly body uncensor when it isn't necessary.
