My rig
2600k at 4.3
7970 1175 1625
16gb ddr3 1866

I can run NSF run

25x14 max no aa no af
And
25x14 max morphological ssaa 8ex aa
At the same fps
Minimum 60+
Average 70-90+

But when I turn on 16x af I loose 10-15 fps straight

Still not bad

And af does drop performance by 10-15%+ even at 19x10 even with crisis etc

Hows the visual impact of Anisotropic filtered pavement and trees passing you at 190mph? Heheh jk jk. I bet it makes a big difference when not in full motion.

does the framerate go from 60 min to 45min with the 16xAF?

 

[aaksheytalwar]

With 16x af min is still in 60s but without af min is usually 70s or so.

Btw am using 12.4 beta
They increase idle temps by 12-14c for my 7970
Was 28-32 earlier. Now 41-45

I would have thought AF even at 16 has a minimal performance hit. At least with the last 5 or 6 vid cards I've owned in last few years. Even at average 70-90 fps, 15 seems like quite a steep drop for 16xAF.
