By chance are you playing in Windowed mode? It is known that when playing in windowed mode FPS drops. With any other UI I have used it has dropped about 5 FPS, from 60 to 55. Maybe the lowest is 50.

However, in NUI, I am seeing a considerable drop in FPS. It does down to 30 FPS when playing in Windowed mode compared to 60 FPS in full screen mode.

Here is the testing I just did:

No addons loaded at all. 60 FPS solid no change while questing around. Full Screen Mode

No addons loaded at all. 53-59 FPS while questing around. Windowed mode.

NUI loaded: 30-35 FPS windowed mode.

NUI loaded: 49-57 FPS full screen mode. Sometimes hits 60.

No other addons loaded but NUI.

I have tried adjusting the frame rate from default of 30 down to 10. It seems to help briefly but not completely.

Hope this lends some insight.
