They should let us disable metal

It seems like Metal does more harm than good. My iPhone used to be perfectly fine before Metal came into the picture.

It's too bad there isn't an option to disable Metal like disabling motion and transparency effects.

I agree.

I think some of the foundation tweaking Apple did on iOS 9 has done more harm than good. It's not just Metal.

Performance is horrible all throughout, and the only improvement I've seen is battery life. And it's not with just one device, but with nearly every single one.

My 6 plus runs at least as smooth as it did in iOS 8. I did initially run into a problem where it would get hot and drain the battery quickly, but I was able to resolve that though a full reset.

Try the control center. I can almost guarantuee you that it's not buttery smooth. In fact, the control center is smoother on the (non-Metal) iPhone 5 than on the 5S and 6 (all iOS 9 ofcourse).

This is ridiculous, on the 5 Control Center is smoothie smooth but on 5S gosh its sluggish as hell.

Here's something funny.I use Chrome on my Air 2 and since Apple doesn't allow Safari's newest rendering engine to be used by other browsers it always had stuttery scrolling which I dealt with simply because of the sync with my Windows devices.Now in iOS 9 the thing takes 2 whole seconds to load but thanks to Metal it's become as smooth as Safari.The OS still lags because of Metal weirdly.

My Control center is smooth on my iPad mini2 and iPhone 5s both running 9.0.2.

I do have issues with 3rd party keyboards since iOS9 (it was very smooth in iOS8:

- sluggish in showing a 3rd party keyboard like Swype (which did release an iOS9 update) especially in Spotlight search on iPhone 5s. On my iPad mini2 is also sluggish in e.g. Safari and some other Apple apps and 3rd party apps.

- 3rd party keyboards not showing sometimes and that it goes back to the stock keyboard (like in Safari and Spotlight search).

Agreed. If it's any indication of performance, GFXBench tests are lower when Metal is used. I also remember reading some forum where a dev compared his app with OpenGL and Metal, and the OpenGL framerate was considerably higher.

Just wait for 9.1

my 6+ runs way smoother on 9.1 then it did on 9.0.2

Yeah. I noticed some improvements with 9.1 on some devices. But many things, such as app switcher and control center lag, are still there.

My control center is just fine.

All I can say is try the reset.

iOS 9.1 Beta 4 is worse than 9.0.2 or iPad Air, though 9.1 Beta 4 on iPhone 6 is just a tad better.
