Is there any way to update the driver in my Radeon Pro 5500M to at least 21.10.1 in order to run Forza Horizon 5 on my computer, my driver is currently at the latest update I have been able to find which is 20.45, I have a MacBook Pro 16" 2019 and I am running windows 10 through bootcamp, thanks for any responses!
You seemed to have the latest Windows Bootcamp driver from AMD download site.
Try this Unofficial Bootcamp site that the author modifies the latest AMD versions to work in Mac Bootcamp PCs unless you have already tried it: https://www.bootcampdrivers.com/
I believe the Red edition is for Consumer GPU cards and the Blue is for Professional GPU Cards. But not sure though.
Since you tried both I suggest you open a Apple Support Ticket and see if they have a newer version than the AMD Site.
If this was a regular Windows PC when you install the Radeon Pro driver it automatically installs the correct version (red or blue) depending what the driver sees what is installed - Consumer or Professional GPU card.
