As you may or may not know, there are serious issues with the Macbook Pro 2012 - 2015 models with dedicated Nvidia GPU. From the moment you start using apps which use the dedicated GPU, the computer starts lagging and filling up memory until it crashes, most likely after a few hours of use. A lot of people have this bug, but simply don't know it because they don't use these kind of apps. I use an external 4K monitor which of course also uses the Nvidia GPU and i have to hard reset my Mac every few hours. It's absolutely crazy. I was wondering how known this issue is here on MacRumors because i don't read much about it. It certainly is everywhere around the net, but the problem is searching for it: since the use cases for this bug are so different, it's very hard to pinpoint that one specific issue.. Some people say it's related to the Metal 2 updates in High Sierra. I was hoping there would be more news by now (because of the betas)..
