Since upgrading our game from 4.13 to 4.14 some of our users reports problems with very blurry textures. Thats why we try to upgrade to 4.15 currently but in our tests the texture streaming doesn’t seems to be better than in 4.14.
This occurs not when starting the game only after driving a long route with the vehicle.
We resaved all Levels in 4.15 and called “Build Texture Streaming” before
In 4.13 we had only small problems with texture streaming.

Also, static meshes will cache the texture streaming resolution appropriate for whatever scale they had when the render state was last recreated. So if you rescale meshes, that can lead to problems. I just fell over that issue and saw your post while researching a solution:
