I can tell you haven't really even looked this subject up. Since I've been working on it trying to get it to work on my end I can answer some of these questions for you:
A CPU can't run it fully. You keep gaming this general broad statement. A CPU can only run the flags and debris at acceptable frame rates (but....see below).
Not all users had to even modify their *.ini files. I am one of them. Before I even reinstalled my second GPU for offloading I was able to set the PhysX to high WITHOUT MODIFICATION. That's how I realized how devastating it is to a non-GeForce system. You can find posters on other forums stating they didn't have to modify the *.ini to get the option to change the setting, but then you'll see them asking why isn't offloading working properly.
None of those screen shots are even showing fluid, which is part of Medium/High settings and those are the features that cost the most performance. Gearbox even addressed this and said a patch will fix the fluid performance issue.
And now you can see why a Radeon + Modern CPU can run PhysX on Low, because there is NOTHING to run. Set it to medium and fluid/debris/cloths will start to bog the system down.
And you claim you aren't turning this into an anti-GeForce subject? As a Pro-AMD user, you sure aren't convincing me.
1. If the PhysX was impressive and demanding as NV marketed it, a CPU shouldn't not have been able to run it;

2. If the CPU can run PhysX without an NV GPU (based on the benchmarks linked in this thread), then NV probably asked the developer to block this feature so gamers who want PhysX think that they must go out and buy an NV GPU.

Anyways, here are the PhysX Low vs. High screenshots.
PhysX Low is basically no physics.
