Antialiasing- best method???

Having some problems with display of some textures and have tried antialiasing implementations such as GL_BLEND. This works OK on my NVIDIA card with speed drop but wondering if there are better implementations?

if you are looking for performance then do not use scene jittering. If thats what you are using then thats the reason for the performance decrease. I would try simple point, line or polygon anti-aliasing. tutorals can be found in the red book. If that still doesnt help your problem, you might look at your textures again to see if they just look bad on your object of something. I actually dont understand why the textures are causing you problems.
