what can i enable to have toon boom runs smoother?

Good Evening, i am producing a 360 rig from the series. Its a comple one, with many cutters and etc. I dnt think i ve done anything unecessary. My viewport gets laggy and zooming in and out comes with some late response.

I wanna ask if grouping nodes help for some reason in responsiveness. Node view is ok, only camera view lags.
My rig is Intel i7 6700HQ 16 ram, gtx 1060.

Is there anything in preferences or enabling anything that can help…? Also if there is , can you point hot to do it…?
Thank you in advance. Cheers community
