I'm animating a scene in Blender and am experiencing some lag. This makes it hard to preview the animation. I'm in solid mode, I tried enabling frame dropping, I tried turning off visibility for some objects, but still pretty laggy. Using v2.79 Specs: Windows 10 Home 32GB RAM Intel core i7 6700HQ @ 2.6 Ghz NVIDIA GeForce GTX 1070
This is a common problem, the more complex is the mesh, the armature, the weights, the more the animation gets slow.
Youn can use various strategies to check your animations: 1 - hide (maybe using layers, even separating some vertices of the mesh) all vertices you can 2 - building a fake simpler mesh, which will be very fast if done using bone parents instead of weighted vertices: i.e. it's very common to build a characetr using the face as it is and using simple cubes or cyliders for torso, arms, legs, parenting each whole object to its corrispondent bone: in this way you avoid lots of calculations. 3 - making a superfast OpenGL render of the scene, which can be analyzed always running in perfect realtime.
Maybe others users know some more strategies.
