eGPU with Retina iMac 2015 for games in Windows for internal iMac display
I'd like to improve gaming performance on my 27" Retina iMac 2015 without having to build an entire gaming rig and finding a place to put another monitor. So my thinking is that I could just get an eGPU and use that when I'm in Windows. As I understand it from reading, the eGPU should work just fine in Windows since there are drivers for most all of the cards. My concern is that I am unclear on whether I will be able to use the eGPU for the internal display on the iMac or if the eGPU will only work . This is the most important piece to me since I am unable to fit another monitor in my current setup. Thanks!
Sorry if this has been answered before. I've been digging for a bit and can't seem to find a solid answer.
Unfortunately Apple disabled the iGPU in iMacs with a discrete GPU. Therefore using the internal display with an eGPU in Windows will involve a workaround and a big drop in performance.
