All Textures Went Blurry

Hi, all my texutres, if leafes from tree, bark, landscape material and any other mesh materials went blurry without any real reason. Restart didnt change anything.

I added a asset pack in my content folder by copyingit via desktop. than i got a asset in the project window and dragged an material into it to replace the original one. Than all went blurry.

Advice plz.

Edit: When i open a material, and just double click on one texture, it gets normal again but not for long

Hi, try to increase your texture streaming pool size. Console command is r.Streaming.PoolSize
