Ahh...
Thanks for clearing that up Humus! =)
I think it should be "put in" D3D asap! (Obviously, hehe)
So, developers just neglected this nifty thing in their "babies"? Shame, as you put it, it would make (i.e) FarCry look better on those who cannot supersample.

Keep up the good work Humus!

Nice! on ati9700 128mb catalyst5.6 - 160-180fps
Good job Humus!

Well the big downside of AtC right now is that it's not supported in d3d and it's not forceable in the driver.

The problem is that supersampling can't solve the problem in the general case. You don't want to average 4 binary values, you want to use one value interpreted directly. Otherwise you get problems with mipmaps. Supersampling doesn't solve that problem.
Alpha blending will always be best, but alpha-to-coverage doesn't need sorting and looks almost as good.

Humus , the SuperSampling tranparency AA is done with a sparsed sample grid and should look really good

Bj�rn, one of the reasons they haven't is because this feature doesn't exist in Direct3D. Very few games using OpenGL use alpha testing to any extent, so this feature haven't received the attention it deserves.

Mr.Pink, no it's not. "Transparency AA" seems more like an selective supersampling algoritm, which I guess will solve it, but be much more expensive and get lower quality.

Jan/CybeRUS, it seems you don't get any multisampling. When that happens alpha-to-coverage won't work. Make sure you're not forcing it off or force supersampling but lets the application decide what AA mode to use.

Hi, it doesn't work on my Geforce 6800 GT and 77.72 driver.
Bug same as Jan

Looks damn nice! Especially first and third screenshot. You should name it Unhumus Engine 2
