Shader model 3

I have a r9 270 and I want to play smite, but when I try and download it says I dont support shader model 3.0. What do I do? I have seen people playing the game with this GPU.

All drivers properly installed?
270 supports shader model 3.0 and then some.

Yea about that I had installed the drivers, but forgot to restart. Sorry guys still fresh to all this.
