Hi,
I’ve tested the antialiasing issues also on one of my Nvidia gpu available in my workstation.
As you can see I get the same antialiasing issue with the Artic shader + visible edges. See the attached rar file to check the high resolution images.
Verdict: there isn’t any issue with my AMD gpu model/drivers, the issue stays in your code.
My Nvidia gpus run with the Studio drivers, not the latest ones, but It doesn’t matter, they work great with Vray, Cycles, Fstorm, D5 and Twinmotion, both cuda renderers/opengl frame buffers.
