eliArie(in lightboost hack-mode) makes it amazing for games.
I just tried this with my vg248qe and noticed a pretty noticeable drop in refresh rate(as expected) because it only enables the strobe mod in 120hz. Despite it looking much more smooth I think I'm going to go back to the generic 144hz default. I wish the mod was capable of running the strobe mod from 144hz -> 144hz(strobed). Not currently available as far as I know :(
It really is only a great benefit for people with monitors capped at 120hz. The mod definitely makes it respond like a CRT would on 120hz but idk I like 144hz refresh rate better.
Hopefully a 144hz to 144hz(strobed) comes out in the near future.
I'll take 120Hz strobed over 144Hz standard any day. There's something magical about moving a window with text and still being able to read the contents perfectly well without any blur :)
Are you sure you're not running into any weird problems? To me the difference between 120Hz<->144Hz wasn't visible regarding refresh rate.
