Nvidia shield controller mapping for PC games

[natapper]

I am trying to play some game on my nvidia shield tablet streamed from my PC that are not already optimized by nvidia. Nvidia claims that this can be done either by adding them to your game library through before experience on your computer or by launching them through your steam library. I have tried launching games such as electronic super joy that do have full controller support but not shield support and if I try to use a controller absolutely nothing happens. When ever I look up how to create a control mapping it is only for Android games and not oc streamed games. Does any one know if there is a way to solve this issue, or do I just need to live with the game that nvidia has optimized?

My other question is does smite have controller support? It is on Xbox one and 360 but on steam it says it is only keyboard and mouse.

Help with both of these questions would be great. I would post the first one on the geforce forums but that is the most unhelpful forum I know.
