I am coming back to use Blender after a bit of a break of a couple of years. I did a lot of work using version 2.7x. I am now trying to use version 2.82a.
My PC is running Linux Mint 19.3 I have 32GB RAM, 16 Core Ryzen Threadripper 1950X and 12GB GTX 1080Ti. I have the nvidia drivers installed and I am using CUDA.
What I find that for a modest sized model (approx 1M verts) version 2.79 is very responsive with zero lag. With 2.82a everything lags, not just zooming or moving the model but also menus and any selection can take seconds.This is in Solid viewport mode, so no textures or rendering.Render speeds are OK.
Are there any ideas as to how to fix this?
Thanks Baz
