indeed the problem is i would like to get rid of the HDRI that i installed (they where 16 K and quit a lot . so i think that might slow blender down . now its really slow . every action i do takes 3 to 5 minutes to be able to do someting else . rendering also is amazing slow. so i hope that if i could remove all the rest (exept the preinstalled) that i could work faster again.
sadly even after deleting the HDRI from my folder where they where installed they stay into blender 2.8 🙁
