Nice tip. Pulling down on Spotlight much smoother now! Thanks!
I believe the lag folks are suffering from has to do with this setting having a bug. When you initially turn this setting on and go to the home screen, there's a one-time jerky animation. I reported this in the beta.
The lag is not there on 6s+. Even in the 9.1b4 thread the lag is confirmed as gone. There seems to be nothing to fix.
Hey you're right. My 6s+ is faster than a 6s. But I did expect that with slightly different hardware.
Same GPU but running more pixels on a larger screen that has a higher contrast and running at 1920. Doing this on the same processor takes more power and cycles from the GPU than the smaller 6s. Same CPU which has to run more to compensate for the larger device and the larger screen. Bigger screen means more LED power to light up the LED backlighting.
Notice i said slightly different hardware. If they were the same, they'd be identical in every way.
Interestingly, this thread is about the 6s and the 6s+ and how the beta is running on your perspective device. As mentioned before, in the beta thread for 9.1b4, there is no mention of issues on the 6s+.
Yup, you're right. More pixels to push on the same GPU. Also, the 6s Plus has to downscale to 1080p since iOS doesn't render at that resolution natively. Look at the GFXBench results for Manhattan on screen. Now, I know benchmarks don't mean everything, but there is a 17 fps difference between the 6s and the 6s Plus.

So wouldn't it be a fairer assessment to run the Manhattan Test off-screen then (as the app suggests to do to compare different models of devices)? When you run that test, you come up with a drastically different score, as in closer to each other.
An no...benchmarks don't mean much sometimes. Especially when you have a picture that shows the same results under different versions of the same program with drastically different results.
Ah, that's when it becomes complex. It depends on whether or not the app display is rendered on or off screen. In the case of the iOS UI, it's rendered on screen, then down scaled for the 6s Plus. And these results are all from the same version of the GFXBench app.
It's fine if you don't notice any stutter or difference, but many people do. Turn on reduce transparency, and launch a 3D Touch menu. It's definitely smoother than with reduce transparency off. There is absolutely a difference between the 6s and 6s Plus if the content is being rendered on screen.
iPhone 6S is still choppy while opening 3d touch menus so I wouldn't say its only an iPhone 6S plus issue. Metal is to blame for both of these phones.
Yeah, absolutely makes sense. GFXBench metal results are much lower than OpenGL results, but the the 6s Plus and 6s are closer in performance (38 fps to 44 fps, respectively). But that's an 11 fps drop from the OpenGL score for the 6s.
