Slow Backface culling

backface culling is very slow when enabled.

Turning this on while retopologizing gives a nice visual appearance to the edges of your low poly. Disabling it, shows a shaded back face around your mesh's silhouette which is a bit distracting.

Turning back face culling on with a 1080 ti massively reduces the frame rate of spinning and interacting with camera.

I don't have a better solutions.

I wonder if I can enable it per object?  Maybe the slowdown is due to it being enabled on all objects in the scene one being a high poly decimated mesh? If I could only enable it on my low poly retop mesh maybe that would give me a similar visual appearance to topogun?

Which version are you using? In the new version, culling is not working on objects which are added into retopo reference list.

Oh that's awesome! Perfect! Just tested it now ! works great !!!! thank you !
