I'll take a shot at this, though it's a bit difficult to explain. OK.
Let's say you've got an array of pixels:
12345
67890
ABCDE
If you try to draw a single black pixel line at 45 degrees on
a white background it's going to hit parts of, say,
45
89
AB
But pixels are indivisable, so each of those pixels is either on
(white) or off (black). Anti-aliasing attempts to correct for this
by painting the various pixels touched by the line in various
shades of grey. When viewed from a distance, the greys blend
nicely and the line appears much closer to the desired result.
This approach minimizes the "jagged line" affect when lines or
edges are at some angle other than horizontal or vertical.
So..."aliasing" is just what happens if you don't have some sort
of "anti-aliasing" technology to solve the problem.
All in all, a relatively simple concept...but difficult to explain!

Anti- aliasing smoothens the edges after rendering a shape. It can be done using many algorithms

4 x (anti-aliasing)
An anti aliasing device uses the technique of minimizing distortion when presenting a high-resolution image at a lower worst quality image. Anti aliasing devices are often used in photography, computer graphics and digital audio among other things.
In digital image processing, the removal of anti-aliasing filter can be achieved by applying a process called deconvolution. This process involves reversing the blurring effect caused by the anti-aliasing filter to enhance the sharpness and clarity of the image.
Because its a shortcut to the advanced settings. Next time, set the Shaders to Low, then switch on the Anti Aliasing. Then apply and go back to the options. You'll see that the AA is back on off, but the advanbce options, Shaders is on High. So it does work.
To overcome the aliasing effect, you can increase the sampling rate or use an anti-aliasing filter before sampling the signal. Additionally, you can employ oversampling techniques or apply signal processing algorithms like interpolation or filtering to reduce or eliminate aliasing artifacts in the signal.
anti aliasing (AA) is the process of smoothing edges so they dont appear jagged. The number associated with it (2x, 4x, 8x, 16x, 32x) is the number of samples taken to smooth it. to make it appear smoother, pixels around an area are added together then an average color is found. basically, the higher the number, the smoother it will appear. however, AA is some of the most taxing work that a CPU/GPU will do and can quickly overwhelm it the wikipedia article here shows very good examples of the different levels of anti aliasing http://en.wikipedia.org/wiki/Anti-aliasing
From the Vibration Analysis Dictionary (www.vibronurse.com): Aliasing - A phenomenon which can occur whenever a signal is not sampled at greater than twice the maximum frequency component, causing high frequency signals to appear at low frequencies. Aliasing is avoided by filtering out signals greater than half the sample rate. Anti-aliasing filter - A low-pass filter designed to filter out frequencies higher than 1/2 the sample rate in order to prevent aliasing.
Turn down the graphics options. Shadows and anti-aliasing are major computer eating elements of games.
It most likely has scratches or a ring my game does the same
