This is just a general question. I don't have any problems with my computer. I just want to know what it is and how it's used to run the game. Thanks.
What is anti-aliaising?

Anti alliasing calculates the grapics for a higher resolution than you actually use, and then reduces the resolution again, taking the average values for the colours in the different high res pixels. So if you're running in 1024*768, it may calculate 2048*1536 pixels, and then averages over each 4 pixels.
The result is that interfaces between 2 objects become much smoother. Instead of having 1 pixel on your screen belonging to one object (lets say a unit) and the next pixel belonging to another object (lets say the terrain), both pixels may now belong to both the unit and the terrain, making the unit look much better 'rounded' instead of squared.
A pretty good example is actually an ordinary pdf file. Open with acrobat, take a screenshot and enlarge that screenshot in paint. You will then see that the letters have various grey colours (unlike these boards).

Also bear in mind that it is very demanding on the GPU, so if you have a low end and bit towards mid level graphic card, you will suffer a serious performance hit.
Actually, only really old graphics cards (which probably are the ones missing T&L support) do antialiasing by rendering everything at a higher resolution and scaling the result down. All newer ones only do that on the edges of the polygons, as that's where it helps the most - right in the middle of a textured polygon bilinear, trilinear or anisotropic texture filtering is (more than) enough to keep any jaggies out.BulMaster said:
If it weren't that way, I should be able to play a game at 2560x2048 without anti-aliasing and get the same framerate as I get at 1280x1024 with 4x AA on my Radeon 9800 Pro - which I sadly don't...
np: St. Germain - What's New (Boulevard)
antialising is the thing that engineers and nerds love. it eats your system, and for that you may see one pixel is better looking than before. When playing game, any game really, it dont matter if you using antialias...exepct to gameplay slows down.
Sorry, but that's just crap.WoodenEye said:
Maybe you don't notice any difference if your CRT monitor is blurring things to hell, but on a TFT at native resolution you notice those hard edges anywhere the edges have a bit of contrast, and even 2x anti-aliasing makes those look quite a bit better without making even a dent performance-wise.
