Woah did i screwed myself this gpu keep this high fps on 1080p on ultra? I barely hit 60 fps with 770 oc on 1440x900 i5 3350p 8 ram msaa 4x wtf.... and this gpu is like 100$ cheaper than mine
I'm guessing it's your CPU. Watchdogs devours the weaker/older Intel CPUs, and all AMD CPUs. Your 3350p is about equal to a haswell i3-4130 (source: CPUboss), so it's not on the performance tier of the stronger i3s or newer i5s.
The FX-8350 at stock clocks averages 50 fps, lower than any haswell i5 (perhaps barring the i5-4430, which nobody is benchmarking in Watchdogs) and about equal to a mid-range i3 such as the i3-4150.
Your i5-3350p is supposed to average
roughly 40 fps on ultra at 1080p (extrapolated from the Watchdogs i5-3550 benchmark, compensating for reduced clocks). Barely 60 fps at 900p sounds about right.
To run it at 60 fps all the time, you'd want at least an i5-4460, an overclocked FX-8350, or an i3-4340 with HT enabled, no weaker (yes, those are all roughly on the same tier).
Also, 4xMSAA is a VRAM and performance killer in Watchdogs, as it uses a deferred rendering engine. Use shader AA and
no more than 2xMSAA. Lose MSAA entirely if you can. MSAA is typically higher quality, but its mostly broken in deferred rendering engines, and forcing it just causes the GPU to bleed way too much performance.
