One of the best updates that came with 7.1 was the ability to see the output composition in the multicam preview. VERY helpful for previewing effects (especially crops, resizes, etc.) without having to switch back to composition view so often.
The problem is now the multi-camera preview monitor forces the output into a lower resolution (1/4 preview or so). This isn't a hardware/driver issue as it worked fine on 7.0.1; wondering if there's a way to force the preview output to full resoltution.

Multicam is one area where realtime playback completely and entirely trumps quality. It's possible your system just can't handle higher resolution playback of all the cameras plus the effects.
The low res preview output occurs whether or not effects are applied to media clips. The stream ran at full resolution just fine on 7.0.1 with no effects, so that doesn't really explain the change. This really effects my workflow because I edit almost exclusively in multi-camera mode on a daily basis. Can't check camera focus at 1/4 resolution.
Ah, that one I can't explain. I can only say that I'm not seeing the same behavior here. The resolution looks just as good after the update as before.
