I recently just installed Vega 64 into my Windows 10 PC. However, upon completion of display driver installation, my Windows desktop keeps on stuttering badly. I look up the task manager and noticed that csrss.exe is using up to 99% of my GPU 3D resource. The usage is not consistent, keeps on fluctuating from 0-99%. Which renders my PC to be inoperable. Once a while Wattman will crash complaining that default settings have been restored due to unexpected system failure.
It only happens when I install Radeon Vega into my system. I tried both Vega 64 and also Vega 56, same issue. I even tried different graphics drivers from AMD, same issue.
However, if I install Nvidia GPU to the same system, no such problem. And I did use "display uninstaller" to remove all GPU drivers prior to installation.
Anyone has any idea what's happening?
General spec of my PC:
Windows 10 Version 1809
Intel 4790K CPU
Gigabyte Z97 Gaming 7
16 GB DDR3 RAM
Samsung 960 EVO SSD
