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

What is the function of an anti aliasing device?

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.


Why can you not get the anti-aliasing in the Crysis demo to work you put anti-aliasing on 4X and when you get out of the menu and go back it's off?

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.


What is anti-alias filter?

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.

How do you speed up the sims on your computer?

Turn down the graphics options. Shadows and anti-aliasing are major computer eating elements of games.

What is anti-aliasing in counter strike 1.6?

Its the smoothing for the game so you dont see the rough edges or rough shadowes ect. But if your computer is slow it will slow it down.

Your computer is probably below recommended specs. Try turning down the anti-aliasing, the resolution, texture quality etc.


What are differences between aliasing and anti aliasing?

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! Dave
