Stage3D and a Mid-2010 MacBook Pro

Question

So, I have a Mid-2010 MacBook Pro running Lion. It has a GeForce GT 330M. According to everything I can find online, my computer should support Stage3D. However, when I try and use an application that calls for it, I get errors about an unsupported graphics card. When I go to the Stage3D unsupported chipset page, it says that my GPU does not support Stage3D in Baseline or Constrained profile.
I found a guy who did some testing of Stage3D vs. WebGL, and he used the same chipset I am using to run the tests.
Is it a driver issue that was fixed in Snow Leopard/Mavericks? Or is my chipset actually unsupported? I would think that a three-year-old graphics card should still work. I appreciate any help that anyone can give.
Complete system specs:
MacBook Pro, Mid 2010
2.4 GHz i5
8 GB RAM
NVIDIA GeForce GT 330M 256MB
Mac OS X 10.7.5
Flash Version: 11.9.900.152

I'd personally trust the assessor window more than the list. It uses javascript to render Stage 3D animation via your GPU, so if it doesn't support it, it won't show the 3D animation.
Since 2004 Apple has been notorious for releasing "mid year" and "late year" models that have minor changes, but are still called the same year model. Sometimes, those changes are for the better, sometimes not.
I had a 2004 G5 iMac that was a 1.8gHz 20". It was made in June. The models made in December 2004 had iSight cams built in and a different GPU, but they were still called 2004 iMacs. Better systems for nearly $600 less. I had a late 2009 MacBook Pro that had a better GPU (512mb VRAM) than my neighbor's early 2009 MBP (256mb VRAM). I'd suspect that the people with 2010 Minis who CAN run Stage 3D have later models, with a different GPU, or some other "minor change" made by Apple that allows it.
Regardless of what it is, unfortunately Flash Player and Stage 3D can't upgrade hardware.
