This is a discussion on Visual issue with textures within the Tech Support forums, part of the Knight Online (ko4life.com) category; I think it may be from the fast loading patch from awhile back? Not sure really just let me know ...
Have you tried to re-install the game?
Don't use the installer to uninstall, use a program like 'Your Uninstaller!'
tried and still bugged
just be thankful its not the white figure-->blue screen <_<
Try re-install direct x, you might need to update to the latest version also.
If it's still not working, you might need to replace your graphics card
