PSA: 2012-2014 15″ MBPr Owners, experiencing UI choppiness? High Sierra’s Metal2 implementation doesn’t always play nice with Nvidia GPU’s.
See these threads, and the many others you can find on this with some research:
I recently upgraded my 2013 15″ MBPr to High Sierra and *immediately* noticed huge UI frame rate choppiness in transitions, stalls when performing graphical actions and generally low FPS when navigating anything using Metal2. This immediately made my Mac feel like an old computer and really bothered me with how bad my Mac had begun to perform.
After further research I discovered this is a well known problem with Nvidia GPU’s on High Sierra. I immediately downgraded to Sierra and everything was back to being buttery smooth again. I thought it worth mentioning to other 15″ users out there. Had I not realized I would have pegged it down to my Mac being an old machine, but on Sierra it feels as good as new.
