To a certain extent, yes. About 50% motion blur reduction, making 60fps@120Hz look like 120fps@120Hz.
However, it will very most dramatically benefit 60fps on LightBoost, because you get the full LightBoost effect at 60fps this way.
There are numerous issues with AMD and nVidia wanting to support software-based black frame insertion at the driver level:
-- BFI can dim the image;
-- BFI can add flicker (not bad at 60fps@120Hz or 72fps@144Hz)
-- You're repeatedly turning on/off LCD pixels at the panel level. If pixel transitions are slow, that can cause BFI to reduce contrast severely.
-- You're running an interference with the LCD inversion voltages (alternating positive/negative values). This can cause LCD image retention.
The most likely thing to happen is a system tray utility that adds flicker, but it would require precision hooks into the drivers, or extremely high priority (e.g. Administrator-level Real-Time CPU priority). But games will still be playing as if it was outputting to a 120Hz monitor which will create some problems. For example, some frames will be rendered out-of-phase with the black frame insertion, and thus be uselessly hidden out-of-sync with the flicker. So there will be strange motion artifacts (moments of increased judder) whenever the frames are out-of-phase with the flicker. But it will do a great job of eliminating motion blur in VSYNC-enabled 60fps games and emulators that ran at a smooth 60fps. Those will be the ones that benefit the most from an external third-party BFI utility. (Maybe we can ask ToastyX or others nicely).
