Why don’t you just open up your last car model and try for yourself? It’s fine as long as you just look at your model. It’s a slideshow as soon as you try to move a vertex. I don’t think I could get any significant work done like that.
I mean, you could probably work with it if you habitually break up your model into many small objects, but I don’t. Even then, 2000 faces, where it becomes unusable for me, is a really really tight budget that has no place in modern CG except as a personal challenge.
I’d consider it unusable performance at the moment. I’m sure they’ll resolve it before release, though. I can’t see the Spring team putting up with it as it is at least.
I don’t know. It needs to get some 1500% faster just to get back to 2.79 levels. Maybe I’m a man of little faith but the prospect doesn’t look good to me.

List of performance issues that we would like to fix or investigate for 2.80:
* Transforming vertices in edit mode on high poly meshes is slow, due to overhead of depsgraph, mesh updates and and batch creation.
BMesh to mesh conversion happens all the time. See check_rendered_viewport_visible, it now always happens when a 3D viewport is visible, and could be quite problematic for edit mode performance.
Manipulate modal callback performance may be problematic: T55458
I’m not worried. Blender is and always will be in development. Coding for this complex bundle of 0’s and 1’s isn’t simple. Its like a web of variables that all affect each other where if one changes, it can mess up others. OpenSubdiv didn’t really work in Blender until roughly 2.76 if I remember right. OpenSubdiv is nice to view high poly models animated. For now I just use low poly mesh versions while animating and use a Subdivision Suface modifier for final renders.
There’s a clear regression in editing performances:
13.934 faces in Vertex Mode.
I don’t understand what’s the problem, since the navigation with this piece of mesh (1.447.039 faces) is very smooth in 2.80, while in 2.79 it’s almost impossible to navigate in Edit Mode.
What I also don’t like it’s that if you select an Object, and you enter Edit Mode, all the faces are selected. Why?
Have you actually tried to grab some vertices and move them around? 2.8 is faster for just viewing, it’s the editing that’s slow.
If you have, and it’s still fast, that would be good news, because it would mean it’s maybe a hardware specific bug and the code isn’t just fundamentally slow.
I can confirm that subdiv operation is significantly slower and viewport is significantly faster, also entering edit mode is significantly slower. https://gfycat.com/SomberContentChicken
Something is not right, because even if we switch to “simple” subdivision algoritm it is still sluggish.
Thanks, it looked like it was only at level 3, I tried the newer version and it only shows Isoparms edges and there’s no option to show the fully subdivided mesh. So it looked even more suspiciously slower than it really is.
Yeah I am sure - hope that they are aware of this and fill fix it asap because whats the point of all the work done when the subdiv module kills usability !
