The why is simple, Dx10 uses the hardware resources more efficiently and transfers some of the cpu load onto the gpu and thus makes FsX more stable. The how is much more difficult and requires an excellent add-on program the Dx10 fixer program that fixes most of the unfinished work MS left out. Also there are many advantageous tweaks to the FsX.cfg and Nvidia Inspector (if you have an Nvidia card) or if you have an AMD card then there are also suggestions from Paul J.
