Possible fix for Nvidia's ShadowPlay

[Borg8401]

Using versions of Dolphin that still contain the DX9 backend if you enable Nvidia 3D, ShadowPlay actually works. Assuming the game handles full screen differently in that mode, whatever the cause the results are the same. Unsure how possible it would be to have this fixed/changed/added but ShadowPlay support would be amazing!

Nothing to do with development.
