I have a Lenovo Z51-70 with Intel integrated graphics and an AMD R9 M375X. I have several GPU related questions: What kind of drivers do I have to install? Where from? How can I set which GPU is used? Thanks in advance
I have a Lenovo flex 4 with an i7 and AMD M465 (I think without double checking). I spent some time trying to force GPU usage and many remedies I found broke the windows drivers. OpenGL seems to be what works for now. Again, I broke the windows drivers a few times until I gave up and settled for OpenGL but here is the page for official AMD support and documentation. I would only attempt if you are willing to fix your machine in CLI or reformat if something goes wrong.
