I had recently my computer formated and, as far as I've seen, the performance in SAMP is even better, ain't freezing never (before format sometimes it frozen). However I tried to install Fifa13 and it's just impossible to play. I find it awkward since I always had fifa and played it with no problems so I guess there's something wrong with the performance of my computer.
I assume my computer is good enough to play fifa so I don't understand what's limiting its performance. Only thing that changed is that I updated from windows XP to 7.
Here I show some SS of dxdiag and from systemlabrequirements (FIFA13)
