Texture pop is determined by how games are written, and there's little you can do about it. You could run the game from a RAM drive, and it would still occur this way, just faster. That you're loading from an SSD VS a HDD doesn't change the mechanics of how the game loads textures, just allows them to load faster. Maybe sit and spin a few times as soon as the scene loads to get most of the textures to pop-in at the onset of the scene.
Some games may have an option to pre-load all texture data, which would of course increase level loading times, but you may search for specific solutions to specific games, and see if there are some extra setup options you could modify to change the texture loading behavior of the specific game engine...
