hi, been trying to find answers to some questions also, and none available.
So from what i understand it works in full screen, i can't test the high res and frequency cuz im still using a supercharged potato(2500k 4.5ghz) and my screen is the same from back then.
From my experience, there is no loss of FPS's, BUT i don't know if it's because of my potato or a software imcompatibility between HALO and games, what get's delay is the light switching, took me days to realize how to fix it, in some games the LEDs would have delay, like like "a second/half of it" to change when you'd move around and your screen changes.
then realized, Anti-Aliasing... MSAA8x, turned it off and the led color change is fast(instantaneous) and smooth now.
Maybe my system can't handle it well enough with bumped up graphics, maybe it needs an update...
Still find this is a great item, only ONE thing i have against ASUS.... 4 headers, 4 screen sides, 3 ledstrips???
ill be buying a compatible adressable rgb strip off of ebay to get the bottom part to work, cuz 50€ for a led strip that SHOULD be included is insane.
(fix these issues Asus)
