First of all, i more than pass the recommended specs
A8 6600k 4.2ghz 6670 Dual Graphics 8gb
But on 720p res i only get 35fps when in a fight and about 50 when flying around not rendering much, which is playable but not good at all
I have Vsync turned off
More aboutfps drops
First turn off Anti-Aliasing, it takes up a huge chunk of performance and then if that still doesn't do it turn off high res shadow. This wont take away much visual detail but should improve performance
APU's have very slow CPU's, and they are very poor in their Dual Graphics mode. You might get better results disabling the APU's GPU and just running directly from the 6670.
