ok I have a 3 gig computer using 512 meg or ram, windows vista home basic and the on board radeon 200 video chip set, I get fps of around 65-75 in every room I go into, only problem is, when I fly or see either a z6m zero, or a moss I lose all fps, but if I fly either plane on internal view I don't lose any fps, anybody have an idea whats wrong ?
