#Dual thunderbolt add in card drivers

But thatвЂ™s just a giant pain to figure out in general. My problem is more with the ecosystem than reliability granted, I donвЂ™t need too much from it, just some screens, networking and USB. I have a friend with a Dell XPS with integrated Thunderbolt, and he gets the exact same behaviour. DisplayPort alternate mode is broken on Windows, too.

My understanding is it has something to do with waking up the controller or something, but I've never managed to get it working 100% reliably. However, in PC land, I have an HP desktop with an HP thunderbolt / usb-c card, and it's hit-and-miss.

Also, the GPU drivers at the time were terribly broken and the MBP would lag like crazy when using it. But by that time, they had already changed the font rendering, so I didn't use that display as often. I remember at one point, after the High Sierra upgrade I think, but I'm not 100% sure on the date, I had some issues with the same thunderbolt screen and the same MBP. One of the screens or the computer itself developed a contact issue many years later, which of course isn't great, but the connection itself has always been rock-solid. And I personally had two displays daisy-chained, with random USB and FireWire peripherals hanging off them. Some 9 years ago, I worked at a place where we had macbooks and Apple Thunderbolt displays. There might be some implementation details, in particular for thunderbolt 3.
