Radeonpro won't activate Crossfire in windowed mode.

This is an issue from all 3 places for all 3 companies(and also in some part nVidia).
SE: Fix lost device context in fullscreen, like every other game on the market for the last 5 years, this fixes it 100%
Microsoft: Update DX9(not gonna happen) to support Crossfire/SLI in windowed modes
AMD/nVidia(how nVidia kinda makes it work): Implement a driver hack(err patch) to split the difference at all times, this leads to sorely underutilized graphics if frame limiting/vertical syncing is turned on.

In fullscreen mode, running on 2 screens so I can see hardware info, I've tested a few different Crossfire rendering modes, and my cards never sit @100% like you'd expect. That makes me happy and sad, they aren't getting too hot, they aren't being pushed to show me how good this could look.
