Hello, so here is my problem:
Having bought just over a year ago a PC gamer on Materiel.net, it has an integrated chipset Intel HD graphic 530 as well as an AMD Radeon RX480.
The worry is that the RX480 graphics card is detected well within the computer (present in the device manager and detected with the GPU-Z software) but is simply not usable.
The research I have done on the various possible manipulations to "force" the use of the dedicated card, especially on games, had no effect.
More alarming still the options that should allow this kind of manipulation on AMD Radeon Setting are not there ... when I get to launch the program from elsewhere: despite the fact that I hold the drivers I always have error message "Radeon Settings are currently not available. Please try again after connecting AMD Graphics".
The only way to open AMD Radeon Setting and use the AMDCleanUp utility and restart the download and installation of the latest version, even though it did not change between two attempts to open.
So much so that I'm not playing heavyweight graphics graphics (since I have been running all the time with the Intel HD530), the big problem is that since recent updates on the side of Blizzard -on StarCraft II and Heroes of Storm - I simply get back on the desk full part for the first but mostly a constant black screen for the second.
The first incident only lasts a few seconds before returning to the game, the second requires restarting the Windows session because no other commands respond.
I have already contacted the support of Blizzard, and over the tiquets they suggested to me to contact the support of AMD ... and so here I am.
So, here are various information about my case, if it need more things just ask.
