I can tell because 1. The resolution is super low (800x600) by default and if I increase it (the max is only 1920x1200)it gets incredibly sluggish, slow and unusable 2.When I click on the radeon AMD settings panel, (which is default in regular bootcamp), it gives an error and it says no AMD driver is installed. Please help, this a maxed out 16"MBP and I only got parallels 15 to use CAD on this computer. The regular Windows partition works flawlessly!
The problem is running Windows through the Bootcamp partition does not work right. Did a clean install of Windows and everything works as it should
Did you install the Parallels tools? When running your bootcamp partition as a VM you are not running the Radeon card natively so those drivers are irrelevant for that.
I should add that I have a Bootcamp partition that I run natively to play games in but then fire up with Parallels when I just need access to do other non gaming stuff whilst in MacOS and it works absolutely fine.
