Windows games do not launch in Bootcamp on a MacBook Pro 2017
I have a 2017 MacBook Pro 2.9GHz with a Radeon Pro 560 with 4GB of GDDR5 memory and automatic graphics switching with in-built Intel HD Graphics 630. The SSD drive is partitioned with bootcamp running Windows 10.
When trying to run Steam or GOG Windows games in bootcamp Windows 10 almost all of them do not launch (Fallout 3, etc etc), and most give some message about a graphics issue (card, driver, etc). I can run very old games (System Shock 1, Dark Forces 1) and I am guessing this is because the graphics are generates in software (not involving either graphics processor).
Has anyone else experienced this problem?
I heard somewhere that it might be something to do with the graphics switching used in MacBook Pros but I can't find that info, and I believe I have seen video of a MacBook Pro 2018 running Windows games in bootcamp.
So I am hoping there is an easy fix?
