Anti-Aliasing on 4K - Varanon - 04-08-2017
A little tip for people with GTX 1070 and 4k monitors:
Running at 4K with Anti-Aliasing is a bit of a stretch, especially x8 since that is necessary for eliminating those pesky jaggies at power lines and some masts.
So up to now I was running at 80 % coverage.
There is a better way, though: FSAA is pretty hard on the graphics card, in fact, it GPU-Dominated scenes (only few objects visible), it cuts the frame rate in half (on Altis, at some places I get 70 fps without FSAA and 36 with x8 FSAA). I tried the post processing AA (PPAA setting in Video configuration) before, but they looked crap.
Unless you are on 4K, that is. while in HD, CMAA does not yield any result, it's great in 4k. It's possible for me to run Arma 3 with the 1070 in 4k with 100 % coverage, and get 70 fps on Altis, and around 40 on Tanoa (Tanoa is dominated by CPU, not GPU).
I suggest trying it out and seeing for yourself. The only thing you lose with post processed AA is the Alpha-To-Coverage (ATOC) rendering for trees and grass.
