Smart Live Selection
Some OpenGL cards do not support Smart Live Selection and will display
errors.
If this option is enabled, live selection under OpenGL is accelerated — only the selected polygons or
points are redrawn, rather than the entire screen.
Textures
Use Textures
You can work more smoothly in the viewports if you disable this option.
This option denes whether textures can be displayed in the viewport. This setting is applied globally,
i.e. it affects all viewports. You can dene this option separately for each viewport using the viewport
settings, which apply to the active viewport only.
Texture Interpolation
Texture Interpolation set to Nearest (top right) and Linear (bottom right).
Texture Interpolation controls which method is used to interpolate the textures when you zoom
objects in the viewport: Nearest or Linear. Nearest uses the color of the nearest pixel in the texture,
causing hard transitions in the zoomed texture. Linear uses linear gradients (i.e. linear interpolation)
to create smooth or blurry transitions in the zoomed texture.
Back Image Mode
If you have loaded a back image in the viewport settings, when you zoom in the viewport the back
image will also be zoomed. Back Image Mode denes which type of interpolation is used for the back
image. Try each mode and use that one that gives the best result.
