Basically it said infrared goggles use digital processing, so there's at least one frame of lag for every image, which can cause those issues. Image intensifying googles are totally analog so there's no lag to avoid that issue.

Well, 24 fps vs 120 fps would technically matter, to the point where at a high enough frame rate you could not possibly tell the difference; I suspect it's more like 48 fps (if it's a constant 48 fps) than 120 *
If there's a digital component to these which causes frame delay, I wonder what the FPS is. Competitive gamers say 120 vs 60 makes a substantial difference. Since the use case is literally first-person shooting...
I could be wrong but I believe 120 vs 60 makes a huge difference only because the framrtate is not actually constant and in certain cases/scenes the framerate can drop significantly, whereas an IR google I immagine will render at a constant framerate regardless of scene.
