What's the problem? Describe what went wrong.

On a high polling rate mouse, moving the cursor with Wii remote emulation causes a severe slowdown.

What steps will reproduce the problem?

1. Set Dolphin to emulate the Wii remote with the mouse.
2. Load the Mii channel and edit a Mii. This is the easiest way to reproduce it in my testing.
3. With a high polling rate mouse (1000 Hz in my case), shake the cursor around. Even on a fairly powerful system, the game slows to a crawl. You don't even need to be focused in Dolphin.
4. Do the same thing with a low polling rate mouse. No lag.
