To be topical, I noticed that the FX Flow wasn't perfectly logical. Sometimes it was on for 2D apps, and infrequently it was off for 3D apps. When it was off for 3D, it was when shutting down a 3D app with another 3D app in the background, or while that 3D aquarium screensaver was running.
I have uber-confidence in the high-temp shut down based on NDA information, so I never thought to worry. Thus, Veni vidi vici.
