Pixelated/low Anti Aliasing problem with curved paths
Not really a GPU bug since it also happens with GPU turned off. But as you can see on the attachment, whenever I draw a curved path in Illustrator it turns out very pixelated/low Anti Aliasing.
Illustrator’s antialiasing was always that harsh and crude, compared to other vector apps, like Xara, for example.
There is nothing really can be done to mitigate it, except for trickery — try to cast the Rasterize effect on the art, with a larger resolution value, and then export the document normally. Or you can just directly export the image larger and then resize and resample it with an external app.
I agree this is not convenient, and I surely vote for this.
