How many elements of the game at the moment are significantly impacted by your choice of race? And what races trigger this?

I've not played through with all races yet, but from what I've picked up the most consistent impact of race is felt when you're a Drow, much less of an impact than expected from being Gith or Tiefling, and that some size related things otherwise, most other races don't have too much of an impact as yet?
