Seems, your hardware can't tolerate any more the bullying of this game. The pictures you showed means that your video card lose some of textures in it's memory. It may be caused by using outdated video card or by physical corruption of GPU RAM. That is not a game problem, but the problem of your hardware. Show your specs here.
Comprehensive information So, you may test your GPU by some 3D benchmark. Try 3DMark or something else. If your video card is corrupted, you will see it while testing. Also you may run the resource checking in PS launcher.
