Ok, lets see if i can help with this:
1) set framelimit to auto
2) Uncheck the "Enable CPU Clock Override"
3) Set Fullscreen resolution to auto
4) Set internal resolution to 1x, not auto
5) Switch the backend from D3D to OpenGL, as it is faster on Nvidia cards.
6) Make sure you have a high performance profile made for Dolphin in the Nvidia Control Panel, and Windows power management is set to high performance
7) What driver version for your GTX 770 are you on?
8) Check Windows update for any updates.
