What sorcery is this Game Booster?

The gains come from tweaking the balance between quality & speed. The GFX settings you see in the game options aren't the only settings, there is stuff that can be tweaked outside of that...plus some of the game setting can simply be straight up overridden on a driver level regardless of what the game says.

So while the FPS increase you see is real, its not more FPS of the same thing.

Do you know what sort of stuff it could be changing, graphics-wise? I can't really see a difference.
And what range of framerates should I expect on my PC, as far as I'm concerned it's underperforming
