Hi Jonas,
your´re welcome! :)
I´ve never used Safari since I´m an WIndows and Android user and Chrome worked out pretty well for me in the M1.
But I just tried scrolling trough the thumbnails on Pinterest and it´s just as you described. Buttery smooth on Chrome (CPU usage about 45%), but very laggy using Pinterest (CPU usage between 25-35%).
I´ve heard that Chrome needs a lot of ressources and Safari is very good when ist comes to battery usage.
I´ve already noticed that some things aren´t very smooth on the M1 that haven´t been any issues with my windows machine. Otherwise things that my beefy PC always struggled with are perfectly fine with the M1. On Lightroom for instance zooming in at 100% and moving the picture around in the library module is a little bit choppy on the M1, but moving the sliders (brightness, contrast, ...) the real time preview is absolutely smooth and in real time. On my windows machine (8700k @ 4,9Ghz, 64GB RAM, GTX1080) it always had a different performance from extremely laggy to really smooth. But never ever nearly as smooth as with the M1.
Also zooming in using Google Earth is really smooth with the M1. I´ve only experienced that performance in Google Earth with my Phones but never on a PC.
It´s a new architecture and a new OS. It´s really impressive but I think there´s still a lot of work to do. For me, the MBA is the perfect combination of tablet and computer and I´m very happy with it. But the issues with the OS updates are indeed a bummer. And the poor performance in Safari seems to be to. Wouldn´t be surprised seeing this behavior in Chrome. But Safari is Apple land. I would have expected them to get at least their own software running perfectly.
But, things aren´t alway that easy und may come other than expected. I´m pretty sure there will be a fix in the near future.
At least you´re not the only one with that problem and it has nothing to do with 8GB RAM.. ;)
Cheers,
Tom
