Shader Cache Issue

I have some Questions about the Shader Caching in this Game.

After every Update or Hotfix the Game is Stutter/Hitching absolutely horrible to an near unplayable State. When i look in the Cache Folder the Game compile the Shaders completely new but don´t delete the old ones. I don´t understand why the Game stutters after an Update, cause the Cache Files are there. I could only fix this when i delete the Cache Folder and restart the Game. Than it stutters the first 2-3 Seconds of every Map and after that Stutter free.

In Dice Twitter Post they wrote that this Folder should not be deleted at every cost ^^. But when i don´t do this after every Update it´s unplayable.

So i think, when you delete the Folder, the Game compiles the most Shaders at Match start and 2-3 Seconds after that. If the Folder is not deleted, it compiles the Files new (and don´t delete old ones) on the Fly when you play.

Is this working as intended? I think not.

Have someone similar Issues?
