As I saw nobody answered to me, I decided to investigate myself. The answer is: d3d: failed to create 2D texture id=2097 w=2560 h=1600 mips=1 d3dfmt=21 [out of memory] No Texture memory available to upload If I understand, the game tries to allocate memory in the ram of my video card for a texture of resolution 2560 X 1600. No validation code to see if there is enough ram before allocating therefore the system crashes (or sometimes it just doesn't display the textures)... You need tu put some validation codes here. I already saw a game that shows a percent bar of the video card RAM and shows what's left. When we choose more graphic options, the bar is fills more and turns red when you're missing RAM. It's just an idea.
