After the next boot of the last save, you may find that many of the items around the area and even plants and earth has become absolutely white. There also may be a significant reduction in image sharpness, making it virtually impossible to pass.
If you experience this problem the first thing is to definitely worth a check for a more recent version of the video card driver or the graphics processor. To do this, go to the manufacturer site, or use special software.
If the update does not provide the desired result, go to the graphics settings in the game and verify the additional effects (reflection, humidity, rain volume, highlights and so on). Depending on the model and version of graphics card drivers installed, you can help to enable or disable these settings. After the change of the values required just restart the game.
