i have Lenovo IdeaPad 500.
in Windows 10
i disabled build in INTEL HD GRAPHIC card.
when i disabled R7 M360 Graphic card or enable it nothing changed.
i install Adrenalin Or Catalyst Driver and found my GPU and install it but in fact GPU not work and can't change the Resolution and lagging its look like driver was not installed and even i disabled both of my GPU cards nothing change and still laging
but intel HD Graphic work fine without problem.
please help me.
i install a lot of version of drivers but nothing changed.
i would highly recommend doing a fresh Win10 20H2 install
you can also try to stay with your win install - follow these steps then:
1. disable Win10 auto-driver-install
2. delete C:/AMD
3. update Win10 to 20H2
4. use DDU in safe-mode to clean old driver
5. install 20.12.1 as your mGPU is GCN 😉
did you do the steps i posted?
