PSA: AMD Releases New Boot Camp Unified Driver R5 (20.45)

[valdikor]

AMD has recently released a new Boot Camp driver (R5, version 20.45) that supports basically all AMD Macs since 2013.

For those that had problems with the previous official drivers or the unofficial modded drivers, this is great news, especially considering that AMD has recently dropped support for all but quite recent GPUs and this new Boot Camp driver still covers machines all the way back to 2013.



Speaking of old Macs with AMD GPUs, I have a 2013 Trash Can Mac Pro with dual D700s, I installed the new driver and it works.

It’s the first version since 2019 (official or unofficial) that not only installs but is stable and runs everything I threw at it - mostly games and as far as I can tell, they run better than before.

I had lost all hope of getting any additional D700 (or trash can Mac Pro in general) support so this is a wonderful surprise. Since the AMD's driver releases target only recent GPUs at this point, this is a great parting gift from AMD for us running these older Mac Pros. I don't think we'll be getting a lot more compatible driver updates for 2013 Mac Pros, from AMD or even BootCampDrivers.com.

I have a 2013 Mac Pro 6-core (D500 GPU). In r5 it says my 2nd GPU is running at 99% constantly. Which scared me. So I downgraded to R3. Which froze my computer after logging in. Went back 'down' to R2 again, where "only" the application tab in the Radeon settings crashes the settings pane and app. Shame, was really hoping here. For anyone experiencing problems jump to R2 Driver package from AMD (BootCamp Drivers from AMD) to download 18.40 driver package or "R2" as it is called also.

Do you have the same issue with GPU 2 going to max in the AMD preference panes? I uninstalled the R5 GPU-drivers with AMD's tool for removing drivers and reinstalled r5 but no dice.

Just to make sure, I have just booted into Windows and checked – no, I’m seeing no such behavior and all is still working perfectly for me with the R5 driver.

It may be a bug related to your specific configuration or to D500 in general, who knows.

Anyway, before R5, the R2 driver was indeed the latest version that actually worked with my D700.

Hi! @valdikor & @AppPatRat !
I have a Mac Pro 2013 with D700 graphics, just installed bootcamp fresh with the latest W10 ISO. Updated drivers using AMD's R2 release. Then bumped it up to R5 and my 2nd GPU is getting 99% usage with it just being idle! When I disable MGPU, it drops down to normal. Any other thoughts or things to try?? I hate to downgrade to R2 like AppPat did. So frustrating that AMD even after 5 revisions all these years, they just still can't get it quite right.

I also can't find anything else online about this exact issue and scenario.

Bump, did you ever find a solution? Running the same mac pro with the same issue. Noticed the older drivers include options about enabling CrossfireX but after updating to 20.45.40.15 we just get the MGPU VR option.
