--- Comment #13 from Nicky nheart@gmail.com --- I can positively say this is the same bug as bug #34052 It only occurs for users running on nvidia hardware with proprietary drivers (not sure about open source ones.)
If running without bumblebee (Only nvidia video card, or using nvidia prime, or DP output wired directly to the nvidia card running on a separate xorg server) it is possible to get all textures in every other run of the game.
If running with optirun/primus you can't get textures no matter how many times you restart the game.
If running on intel gfx you can all textures no problem.
So bug is with nvidia/nvidia+wine and is being exposed much more through the use of bumblebee
