Testar hasn't posted the precise model number, so it's difficult to provide accurate and complete advice.
Does this notebook include AMD switchable graphics?
AMD Switchable Graphics Technology
If so, it'd need drivers for both the onboard Intel graphics controller, plus the separate AMD controller.
I have no personal experience with it (or nVidia's similar Optimus scheme), but it's not impossible that Testar would need both Intel and AMD graphics drivers.
