Hallo folks,
i have a problem with my bootcamp Radeon graphics Driver. Installed Win 10 via bootcamp on my iMac, installation was no problem. After the Win 10 installation, i installed the bootcamp graphics driver for the Vega 64 from bootcampdriver.com v. 19.3.3. I used the including tutorial and followed it step by step (uninstalled the bootcamp radeon driver with DDU...installed the new bootcamp driver 19.3.3 after a reboot). Win 10 recognizes the Vega 64, no error message and no yellow triangle (error 12). To control the performance of the eGpu i used some benchmark. Heaven Benchmark makes a performance jump from 42 fps (in Mojave) to 62 fps (in Win 10 ), Settings 1920x1080, extreme, 8x antialiasing. But in my opinion it should be a little bit more, compared to other results in this forum. In "The Devision 2 (the reason why installed Win 10), i get 40 -60 fps on high graphics options and  1440p. Most of the time it is 50 fps. It seems to be a little bit low. CPU is about 50% utilization, GPU 85 %. 
But what surprises me most is that I don't have Wattman settings. Just the global settings for the graphics card. And every time a want to use the eGpu, i have to uninstall the eGpu via device manager and reboot to avoid the error 12. What have i done wrong?

Make sure you also disable Windows auto-install device drivers. Run DDU again and click OPTION to disable this feature and remove AMD graphics drivers completely.

After initial issues I was able to solve some problems. Obviously, there is no function to undervolt/overclock in the bootcamp graphic driver if a dgpu (radeon pro 580) is installed. But afterburner helps me in this case. I have set my vega 64 to P6 975mA 1600MHz P7 1000mA 1680Mhz HBM2 1090MHz. Have checked these settings several times with HEAVEN benchmark at 1440p Extreme 8 x Antialiasing. Everything works fine, no crashes. I would like to run the Time Spy benchmark too. But when I set up the egpu use in graphics settings > applications > high performance, Time Spy does not use the egpu. Where can I find the right exe?
