Performance improvement - Viewport

Hi All,
I am working on blender to do the re topology work. I have imported the obj file from ZBrush.
The view port is working very slow while making the re topology. please let me know ,do i need to change any specific settings for that?

Thanks

Blender, atm, has problems with the viewport, especially on high poly counts, which I expect when hearing you imported a model from zbrush.
I hear good things about Zbrush’s Decimation Master. Maybe try to lower the polycount first?
What’s your hardware specs?

I already decimate my model. This work perfect in maya but not in blender.

what are your specs? thats important too to manage retopology on pretty high poly sculpts
