what are artifacts?

Artifacts are visual abnormalities that appear in a 3D rendered scene. Things like misplaced textures, incorrect textures, wierd geometric shapes (either 2D or 3D) that appear where they're not supposed to. For example, floating triangles in the sky or a tree that's using a brick texture, would generally be considered artifacts.

A dying GPU (or Vram), Too much heat, Too hard of an overclock or too low of a voltage will all cause artifacts.
 
glitchy shadows(only on one game i get this, because the shadows arnt done well.) and environments arnt considered artifacts r they?( in oblivion a part of the land will look different from the land im on untill i walk closer.)

Maybe it's your AA settings :)

I get glitchy shadows in Oblivion... I'd say that they're NOT artifacts, but mis-renderings by a poor driver.

Walking towards something that's far away changes how detailed it's drawn. It's a feature by the Oblivion engine to lessen the strain on your GPU if you've got ALOT going on... IF everything was drawn at full quality, especially far away land, you'd have frame rates in the 20s. It's NOT an artifact.

That doesn't sounds like a gpu artifact. The distant horizon textures in that game are screwed up. Try using a level of detail (LOD) mod.

Strictly speaking, artifacts are abnormalities in any image (not just 3D). For example, if you compress and decompress with a lossy compression scheme, you can have small but visible changes in the image - these changes are referred to as artifacts of the compression algorithm. This can happen with both still and video.

Similarly, any processing can generate artifacts if it results in a change in an image. E.g. taking an image and showing it at a different resolution than used for recording the image can introduce artifacts.
 
Artifacts are remnants of ancient civlizations that archaeologists dig up hundreds or thousands of years later.

Glitchy shadows in Oblivion are a fact of life. The shadows in Oblivion suck mad donkeys, in my opinion.
 
^ agreed. If I turn on self-shadows, people (especially their faces) have big stripey black squares where the shadows should be. This is on an x850xt-pe with cat 7.1's. Sometimes they look alright, but whenever you get close (like when I talk to someone and it does the zoom-in thing) then the shadows go all to hell.

I should check my apartmentmate's xbox 360 version and see if it's any different.
