Does Blender 2.8 use OpenGL to store and project brush alphas like most modern software architectures do? Because I'm experiencing major brush stroke lag on low poly meshes with 4k textures.

  • $\begingroup$ We need to see screen shots of what you are working with, as well as settings pertaining to the brushes. You could very well be experiencing lag due to painting with a large brush encompassing a large area of the mesh target that is like painting 2-4k at once. $\endgroup$ – Craig D Jones May 30 '19 at 16:02
