# 3D effects

Disable Textures | NOTEXTURES | Remap all textures with a white texture (Direct3D only).
3D wireframe | WIREFRAME | Show graphics in wireframe mode. This option works with Direct3D and OpenGL programs, but not with DirectDraw programs.
Disable Fogging | DISABLEFOGGING | Disables the fogging effect (Direct3D only).
Clear target viewport | CLEARTARGET | Forcefully invokes the Direct3D "Clean" method on the target surface every time the "BeginScene" method is invoked. Most games already do this, but some omit it because there were no undesired effects on the computers that were in use at the time. Running these games in windowed mode on modern platforms may show trails of previous frames. This flag cleans up graphical artifacts from old frames, resolving this issue.
