L.A Noire DX9 vs DX11

And I don't say 'runs better' because fRAPs can tell me or can feel it's a bit better. The game horribly sluggish on DX9, even the Menu! But on DX11 it's smooth and fine - OK big, daylight scenes a bit choppy. Any I use Win7 32 bit Home Premiuim and a Geforce GT440 1 GB graphics card.
