Basically, the game will play normally, until after about an hour or two, some textures will not load, and will appear completely white.
And it begins getting worse and worse over time, and early in, before things are 100% fudged, it causes the backgrounds of the menus (Such as the character menu) to be nonexistant, meaning its almost impossible to use, and all conversation backgrounds will go completely white.
If you continue without restarting the game (The only discovered way to fix it), it will deteriorate to the point of the entire space background, all of the ships, and literally EVERYTHING to be completely white, rendering the game nearly unplayable, as everything is white, so everything camouflages into the background. If you try and log out to fix it, it will not fix. You HAVE to restart the entire game.
