I have a 15R 5337 and just can't install any AMD driver, neither by AMD installer nor Windows Update. I'm using only the intel HD driver and the performance has decreased. When the amd driver finish the install, everything just frezze and when i try to reset, windows reboot for ever, and just stop when i delet the driver. I'm using Win 10 Enterprise, also all drivers, Directx and BIOS are updated!
You must use Dell Downloads for your laptop since drivers are customized by Dell for your exact motherboard. You cannot use AMD drivers from their website. Laptops come with the correct drivers and are rarely if ever updated. Install the original drivers from here--
