Before digging in with my 2015 13" rMBP
@knobchse sorry to say, but no improvements at all. for me, windows 8.1 made it just worse, never actually made it to work in there... biggest success rate was for me with win10 anniversary update, 372.78 driver version, and no scripts running, and booting WITH egpu plugged in and turned on already
@sampuetho hmm thats odd. Because it seems to me that the Early 2015 rMBP 13" models all have the same boot issues. Yet @hdogan says that he's had no issues at all with Windows 8.1 ( https://egpu.io/forums/mac-setup/mbp-egpu-detection-issues/paged/3/#post-10714).
Have you had any more successful attempts? Do you have to go through the whole driver reinstallation every time you want to game?
