[Solved] Bootcamp Graphics Driver Problem eGPU Vega 64
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?
