I tried to run watch Dogs today after finding 30 minutes of free time.
I tried 7680x1440 but it seems that the game doesn't support eyefinity out of the box and there is currently no fix yet to fix the FOV and HUD. Widescreen Fixer or Flawless Widescreen don't have a fix yet.
So I decided to give it a try on my middle monitor, which is the
Samsung 4k U28D590D. I tried Ultra settings with MSAA and MSAA is totally broken on 14.6 Beta and watch Dogs. It was a total slideshow... like 2 fps.
I found out that FXAA does a pretty good job without hammering too much on the performance.
I get around 60fps with my current config
- i7 4930k @ 4.5 Ghz
- Corsair Dominator GT 2133 Mhz 9-11-10-27
- Crucial M4 SSD
- Quad R9 290x (Stock 1000/1250)
- Everything is watercooled and nothing is throttling

When I go to an open area I see big FPS dips. I don't feel that the today's games are optimized for PCs. It is very frustrating to have good hardware and not to be able to run everything maxed out. In 2008, my BFG Tech 8800GTX OC 2 was running every games I wanted
I will have more time maybe tomorrow to test thouroughly but I bought new toys that I need to test today.
