I have re installed the game on my SSD and the FPS hit is still there, only thing the SSD did was fix some of the stuttering issues which wasn't a huge problem before.
This also affect my other system, but drastically worse. FPS at times set right around 3FPS when before it was better, though still worse then my AMD system.
OS: windows 8.1 Pro x64
CPU: i5 2500k 3.3ghz
RAM: 8GB Corsair Vengeance 1600mhz
MOBO: Dell OEM Motherboard
GPU: ATI HD5850 (Modded bios for dual monitor flicker fix)
PSU: Antec TruPower 430watt
I know the 5850 is a 6 year old card, but it use to get more FPS then that, even on low settings.
I don't understand why you all put more things into the game when the game runs like a pile of crap, it would be 10 years down the road before anyone could break 60FPS in a city.
