I decided to upgrade my PC, because it couldn't run many games. It had an integrated gpu in my cpu (CPU: AMD A10 5800k; GPU: AMD Radeon HD 7660D (800MHz)).
After installing an AMD Radeon RX560 2GB (seemingly undamaged, new) and relevant software, it seems to me that my graphics card isn't working, because games get worse fps than before.
I feel like I have not installed the right software, but i have tried every tip I could find online.
I have installed/updated:
Radeon Adrenaline 2020 Software and its:
At this time my graphics driver version is: 26.20.15002.61
The old GPU is offline and the new one is online.
I have encountered an error saying: The graphics card driver does not support OpenGL.
I have scanned my PC for viruses, found a trojan horse, removed it, but nothing changed.
