Sudden FPS drops

Our systems are the same expect that I have 16 GB ram.

This game should've ran at least on high with not trouble however I can't even play it straight,fps drops down to 5's and 0'es which makes it intolareable.

i feel u, trying different settings and various fixes nothing helps...

This game is so badly optimized it ain't even a joke. 

A lot of people criticized Ubisoft's Watch Dogs for it being so unfair towards PC gamers but this game takes an unenviable second place in the one of the most BADLY optimized PC titles from Bioware. I have superclocked GTX 980 and I am only able to run at 60fps in HIGH settings as opposed to ULTRA which really is ridiculous considering the fact, NVIDIA Geforce Experience suggests I max out every settings for a smooth 60 fps experienc.e 

SAme here, but only after the patch I installed today.  before that I was getting about 30-40 fps on ultra

I've had no issues whatsoever with performance, running on 1 x 290x i get 45-60fps and running Crossfire i get 90-105fps. 

Nothing seems to have changed for me since release. Cutscenes run at 30fps (haven't used commandline argument).

Yes i do use Mantle.

i7 4770K @ 4.4Ghz

32GB ram

Windows 7 x64 Ultimate 

2 x 290x Reference (custom fan profile/3 screens).

Settings :

Ultra/fadetouched/HBAO Full/4 x MSAA. @ 1920x1080 

When i use Eyefinity 5760x1080 i get around 45-55 fps no drops.

When only 1 screen is attached i get about 5-10fps more on average.

jep, its just saddens me... 

i had same problem, with other games with fps drops and my solution was disable origin overlay in game, and the games working great after disable, maybe can work for you

yea i know.
