Hmm...thunder350 I smell Microsoft employee.... phyrburn you're card can't play lost planet it's too old! You need a new one that supports shader model 2.0! And you can't play dx10 version cuz your card HAS NOT DX10!

I don't see much difference. I can see that motion and texture are not the same, motion is a little better with dx10, but the textures are sometimes better with dx9 and sometimes better on dx10. For me dx9 is the winner cus he leads in fps.
