iv'e seen people sculpt meshes around 5 mil verts with no lag whatsoever, but everytime i come close to like 1m and above the lag starts to be noticeable and soon any sculpting becomes unusable.

Im well aware that this requires good rig, but i belive that with 32gb ram and gtx1080 i've got that covered.

Tried dyntopo and multires, seems that multires is slightly better performance wise, but it is still far from smooth on high poly counts.

using blender 2.79

    $\begingroup$ What kind of lag? If it only happens at the end of a stroke, it's because the mesh has multiple users, including the fake user. $\endgroup$ – Michael Glen Montague Feb 15 '19 at 21:54
  • $\begingroup$ but is he referring to lag when nagivating or when sculpting? $\endgroup$ – Michael Ben David Feb 15 '19 at 21:57

    $\begingroup$ CG Boost has some tips that speed up sculpting to 30-100 million polys, does this help you? youtu.be/fw32i2dBfEo $\endgroup$ – Freespirit Jun 7 '19 at 14:22

but you are referring to lag when nagivating or when sculpting? dyntpo its better for having less polycount when sculpting but it affects the mesh and without a way to to delete it or undo what you done after finished the sculpt and also it works with triangules instead or quads. multires instead save this information in the modifier and makes a even subdivision in the whole mesh, but some times not necesary to have all the mesh subvided in areas that you wont sculpt, and it stays the original polycount and topology of the original low poly base mesh used. but you can use both like he does https://www.youtube.com/watch?v=Nc3cRVG3me4 also avoid to have matcaps and the outline select option checked because it will put it more slower when its very high poly.

One of the major complaints with blender 2.8 right now is that, despite all the work and effort put into the sculpt mode, dynatopo, what-have-you, the vertex cap for sculpting is actually very low. My rig starts struggling at about 3 million polygons, and this is the same rig that can easily pull about 40 million on a Z-Brush sculpt. For that reason, I am using Z-Brush for anything I anticipate going over 2 million vertices. When I retopo, I also make dang sure to make sure the reference mesh is decimated to under 2mill as well, and use X-Normal to bake instead.

And remember, this is with 2.8, you claim to be using 2.79, which is before all the updates and speed improvements. As such, I am not surprised you are reporting the performance that you are. You can get a small speed boost by bumping to 2.8, but I would actually recommend looking elsewhere than Blender for the time being if you want to get very detailed.
