Other passive systems do not loose resolution. There is one very important thing you need to always keep in mind :Resolution is a property of the display
Active/passive is a property of the glasses
There is no link between the two, except when sales reps and journalists don't want to spend the time to explain and just rush to conclusions to say "I have only two products on shelf and product X is better than Y".
There are other ways to do 3D for which these shortcuts are not appliable, and dual-projectors is only one of them.
I have run both a passive polarised and the Omega system on my dual-projector. I can run them both at full 1080p60 (with actual 1080p60 per eye). The only requirement is that you need an actual 1080p60 source, at the moment the only one available is to use a computer with dual-outputs. (preferably synchronized outputs)
It is theoretically possible to use a brand new graphics card which supports hdmi1.4 @ 3GHz or DisplayPort 1.2 which both support stereo 1080p60 (Nvidia's and AMD's latest cards have both), but there are no converters available at the moment for dual-projectors.
Regarding viewing angles, with Polarised projection it depends on the quality of the silverscreen. Crosstalk increases with the view angle, for professional screens designed specifically for 3D the manufacturer usually publish charts depicting polarisation extinction ratio variations according to view angle. The best silverscreens typically have poor extinction beyond 20°.
Omega crosstalk is not affected by your position in the room, I tried at home and went all the way up to the wall there was no visible crosstalk, so the viewing angle is the same as the absolute 3D comfort viewing angle due to picture distortion which is generally estimated around 30~35°, regardless of the 3D screen technology : to go beyond you need a VR content that does head-tracking and adapts the projection according to your position in the room.
The only way to get crosstalk from the Omega system is to turn your head far away from the screen (make the screen only visible in the corner of the lens), then you'll see some crosstalk.
