I guess what he means mostly is actually high frequncy FPS variation in video frames rendered by an application. So really much the same as the electronics definition for jitter of a clock signal.
The thing is, he doesn't in any way demonstrate which of his kernel config changes accomplished what results in his tests, if he actually has done any repeatable testing at all.
Now, maybe you can't get FPS variation or standard deviation out of Doom 3, but shouldn't that be the starting point? Doom 3 is open source now after all.
I dunno, maybe there's something to this but the documentation and presentation leave something to be desired.
