Directional detection is an important way to detect dark matter. An input tothese experiments is the dark matter velocity distribution. Recenthydrodynamical simulations have shown that the dark matter velocitydistribution differs substantially from the Standard Halo Model. We study theimpact of some of these updated velocity distribution in dark matterdirectional detection experiments. We calculate the ratio of events required toconfirm the forward-backward asymmetry and the existence of the ring of maximumrecoil rate using different dark matter velocity distributions for $^{19}$F andXe targets. We show that with the use of updated dark matter velocity profiles,the forward-backward asymmetry and the ring of maximum recoil rate can beconfirmed using a factor of $\sim$2 -- 3 less events when compared to thatusing the Standard Halo Model.
