240hz looks better than 360hz???

I have a 271qrx and mostly play osu lazer. The game is can be capped at a multiple of refresh rate(x2, x4, x8), and a max capped frame of 1000fps. Since 360hz can only be capped at 2 times(720fps), i reduced the rate to 240hz, and capped it at 4 times. I felt like it's much more clearer overall and found it's strange. So i went to ufo multiple frame test to confirm. To my surprise, at 960 pixels per second, 240 seems clearer than 360hz(the white dots on the ship body is clearer), while 360hz is clearer at 1440 pixel per second(x4 the refresh rate). I'm a bit confused about this phenomenon.

My 360hz display has an ultra low motion blur mode who's max setting is 240hz, so, could be that sort of thing.

might be down to different overdrive levels? though an OLED might not even need OD, so idk, just a guess

There are multiple reasons.

1. Framepacing. 240fps @ 240Hz will generally look clearer than 321fps @ 360Hz. The "framerate = Hz" improves motion clarity since fast jitters adds extra motion blur. Jittering worsens motion clarity.

2. Overdrive may be better at 240Hz than at 360Hz. LCD GtG can be a significant percentage of a refresh cycle. When GtG reaches approximately half a Hz, you can see smearing.

3. System precision. Even if you're capping at 2x or 4x Hz, you may notice that the game's framepacing precision isn't that good. It's easier for a game to do framerate=Hz or (framerate*integer)=Hz if the numbers are not quite as high.

That being said, if you want improved clarity, you may notice that many 240Hz OLEDs has clearer motion than 360Hz LCDs. Same is true for a 480Hz OLED versus 1000Hz LCD, because the non-zero GtG of an LCD creates a big penalizing effect when GtG-times enroach refreshtimes and frametimes!
