In computer graphics, '''texture filtering''' or texture smoothing is the method used to smooth textures used in 3D models. Some consoles use texture filtering.

*Very fast.
*At integer values (eg, exactly double or quadruple resolution) it's practically "unfiltered".
*Unfiltered pixels tend to look odd, with some being thicker than others. This can result in pixel art losing clarity, and text may become hard to read.
|-
*Looks better than nearest neighbor for 3D games.
*It's the least system-intensive form of texture filtering/scaling.
*At low resolutions, 2D games tend to become very blurry. This is especially noticeable in 2D games, and low res 3D games.
*If you have the hardware to do so, look into more complex filtering methods to preserve clarity.
|-
*Looks better than bilinear filtering for 3D games.
*As with bilinear, low-resolution games will more than likely appear overly blurry using this method.
|-
*While it is inherently destructive, some games (eg. Yoshi's Island) may benefit from this filter, as it preserves the cartoony look.
*Artifacts are common.
*Curves and slopes that aren't 45° look jagged compared to everything else.
*Worse at some things that xBR excels at.
|-
*Less system-intensive than HQx and xBR.
*Adequate if it's the best option available (e.g. in Pete's OpenGL2 plugin for PSX emulators).
*Edge detection is horrible.
*Artifacts are common.
*Archaic. The alternatives are much better.
|-
*Looks great for many 2D games.
*Edge detection is improved over HQx. This gives textures smoother curves and slopes, as well as fewer artifacts.
*3D games look great with it as well.
*Posterization is common. There are deposterization filters in some emulators (e.g. PPSSPP) that can aid this, however.
*The finer details of the textures/sprites might be obscured by bad edge detection.
*Worse at some things that HQx excels at.
