Anti Aliasing Question.

[Jale]

Since I got a new video card (Radeon X1600) I've been interested in the new features, including Anti Aliasing filtering, but I see not everything is anti aliased (sprites). Look at the pic above to see what I'm talking about:

I want to know if there's a way to apply anti aliasing filter into sprites or textures with alpha channels. If there's no way, is that normal?

Probably not, unless you replace it with a higher resolution texture. It may simply be low texture. AA is nice, but it is power hungry and cannot always fix everything.

I see. I thought it was an issue with my graphics card.

[Zach]

Only way to be sure is to look at the exact same spot with AA turned off and blow it up, or look for a plain visual difference. Then you'll know for sure if you simply need to get a higher resolution texture. But it seems clearly obvious it's a texture issue, as you clearly have anti-aliased imaging going on, while other things still look pixelated like a blown up image, etc.. (Mario lives remaining, Lakitu camera, etc)

I've done a small research and I see it's a normal thing; sprites cannot be anti-aliased, only 3D geometry.

Interesting what? You never knew about anti-aliasing?

Looks like a spammer to me.. Based on all his other posts

Hah, i didn't..

The reason for this bump:

This could interest the pixel whores like me. To enable anti-aliasing on sprites, you must enable adaptive anti-aliasing. The impact on performance is very high, so it must be used with fast graphics cards.
