I have an Acer Asprire 3 a315-42g-r6fz notebook, which has the following configuration:
GPU: Radeon 540x 2GB GDDR5
APU: Ryzen 5 3500u with Vega 8
RAM: 16BG DDR4 2666Mhz
The problem my notebook is presenting is that in both radeon software and windows my main video card is Vega 8, I wanted to use obviously my dedicated video card Radeon 540x, to this way get more performance.
The graphics selection is handled by Microsoft. Go to your computer 'Dislay' option and scroll down to graphics.
the integrated video card is as primary in the amd redeon software, and the dedicated video card is as secondary.
Yes it is normal....you can't change which graphics is the discrete or vice-versa. You can only assign the graphics like I showed you.
