Dolphin on New Rig - A Few Questions (Super Mario Galaxy)

[Dolemub42]

Hi,

I got a Intel Skylake 6700K system OCed to 4.5 GhZ. 64-bit Windows 10. Geforce 770. Playing at 1080p. Latest beta built. Playing Direct3D.

I have a few questions, concerning my initial playthrough of early levels in Super Mario Galaxy.

1) How do I get rid of the mouse cursor in fullscreen mode? It is distracting when viewed alongside the ingame cursor.

2) I notice that the game is prone to suttering, especially noticeable with the audio. This is almost, but not entirely, eliminated by playing from a solid-state drive. Is there some other way to help this?

3) FPS is super smooth almost always, but sometimes when initially entering a stage of level it slows way down temporarily. Is there a fix?

Thanks.
