What is Artifacting?

[DGB]

I've done some research but haven't really come to a good conclusion on what it is. based on what i have found, it seems that my GPU is artifacting. can anyone tell me what artifacting exactly is?

(sorry for the sounding-like-essay post)

They can be lines, little splotches of color, or VERY little white or green dots.

Post a picture of what's happening. Artifacting comes in many forms.

It's hard to take a picture because when i think it is happening is in minecraft when i am moving and when i am still it doesn't happen almost at all and it only lasts less than a second

If it's only one game, might not be a issue with the card. Test other games and benchmark. See what happens.

Does it look like this? lol

Welp, there's tons of explanations for what artifacting is, but here's my 2 cents if you want it.

 

Broadly speaking, artifacting in any 3d application is essentially any unwanted or unusual rendering error or or display corruption which includes, but is not limited to:

 

-Stretched polygons (like the protruding models on the left side of the above image)

-Strange coloration/flashing

-Noise/snow (lots of that is spoken of when talking about overclocking)

-disappearing models

-"Rolling" flashes or colored orbs

 

In a lot of cases, some artifacting may come down to GPU driver bugs, or game/application bugs, others may be pinpointed to certain causes. Some more widely known causes/effects (some of which I've experienced) include:

 

-"Rolling" green or multi-colored pixels on a certain part of the screen - possible loose display connector

-Flashing red orbs/missing polygons - Marginally unstable GPU Core overclock or lack of voltage for said overclock

-White flashing "glare", elongated red flashes, or brief flashing changes in image coloration - Unstable GPU Memory overclock

 

Those are a couple among numerous examples. First and foremost, if it's limited to a singie application, it may be application specific. Additionally, if you've overclocked, depending on the type of corruption, you may need to back off on clocks, if you haven't overclocked, then there may be a hardware issue, which sometimes manifests itself as flashing green (or multi-colored) blocks, or even display crashes. It could be a failing GPU, faulty Memory module or degradation due to overheating.

 

Now if you don't quite know how to go about things, depending on some of the above you can start by Checking your cable connections, then moving on to going back to stock clock speeds on your GPU (Again, IF you've overclocked it), monitor your temps temps under a good gaming load for anything in the "worrying region" (90C+) and then move on to driver uninstallation/reinstallation, with an additional step to that being the shuffling back and forth between earlier and later releases. Again, if it's only in 1 game, and depending on the type of corruption, it might be driver/game specific, so don't go tearing down your computer just yet.

 

P.S. Apologies for the long-winded post, as you mentioned just minecraft, but in the event of corruption appearing anywhere else, *points up*

Are you thinking of screen tearing where the upper and lower parts of the screen are misaligned about a horizontal line? Screen tearing is normal and can be fixed by turning on V-sync in a games options.
