Judging from others pics and video reviews, OD80 looks slightly better than that and OD120 looks a lot better with slightly more motion blur.
This morning I was taking 480fps 720p videos to compare OD80 with OD120.
I forgot to switch back and I just realized that I played the entire day with OD80 without even realizing that I was not using OD120.
OD80 is usable, but I'd say only at 280hz since 240hz creates way too much overshoot, OD120 is basically overshoot free at 280hz that's why I consider it to be the best OD at 280hz even tho motion clarity is
slightly worse than OD80.
At this point it really comes down to personal preference, I'd never use the Zowie with AMA Premium if that's the amount of overshoot you get, even the VG259QM with OD80 at 1920 Pixels Per Second has an overshoot trail 3x smaller than the pictures provided by PixelDuck at 960 Pixels Per Second (half the speed of the UFO).
Can -0.7ms of Rise/Fall G2G justify using OD80? OD80
does indeed provide better motion clarity but the amount of transitions suffering from overshoot is undoubtedly higher than with OD120.
I'd say that if you are very sensible to overshoot OD120 will not be an issue for 99% of the users, it's all around the best overdrive for this monitor at both 240hz and 280hz.
OD80's overshoot can be a dealbreaker
especially if you play games with dark maps, if you've ever played Overwatch on Lijiang Tower you'll notice a bright trail following moving objects, today I played Apex which has very bright textures and I didn't notice any overshoot.
The total response time of OD80 is 6.4ms compared to 6.1ms from OD120, this is probably due to the time it takes for each pixel to "recover" from overshoot, but the rise fall is 1.9ms(with 1.9ms dark avg) compared to 2.6ms (with 2.4ms dark average), this means that you'll have 1.67ms to see a 90% perfect transition compared to 0.97 with OD120.
Motion clarity is not dictated just by the amount of transitions inside the window, it's important to see for how long you can see a 90% transition rise transition.
If a transition is as slow as 4.1ms in a 4.16(240hz) window then you'll perceive 0.06ms of an acceptable transition but your eye already spent 4.1ms watching a color shift from X to Y and the next transition will instantly start so image persistence after a 90% rise is a good indicator of motion clarity.
We are not machines that can decide to see the perfect ending of a transition at the perfect time, we
perceive motion clarity, we
perceive overshoot, we
perceive ghosting.
Some users will say that OD60 or even OD40 are better at 280hz because they are very sensible to overshoot, some others will say that OD80 is better because it provides better motion clarity and they don't see any overshoot.
It really comes down to personal preference: response time tables, respone time charts and motion blur testings are just baseline indicators of motion clarity,
the perception of motion clarity depending on the individual sensibility to overshoot and ghosting is way more important.
