Even with just 1x290, it still isn't playable for me, doesn't matter what settings I use, it will stutter like crazy.
To me it just seems like people either:
- genuinely are having a perfectly smooth experience
OR
- just aren't as sensitive to stuttering as others
Unfortunately I notice stuttering no matter how small it is and it instantly puts me of any game.
The annoying thing is that it will probably never be fixed since far cry 3 and watch dogs still stutter away on my PC.... Saying that, the modding community managed to get watch dogs to run really well so hopefully someone can do something else for FC 4.
