I've tried to fix this error for many month, now I finally gave up. No one game see my discret card Radeon R7 M440. Even in Windows Device Manager it shows like R7 M340 with latest AMD drivers. I don't know how to fix it. Battlefield 4 crashes with directX error that card is disabled. Rainbow Six Siege seeing it like Radeon R7 Graphics with GPUAdapter = 0. With GPUAdapter = 1 it sees integrated card only and says that there is no discret card. I tried everything. I will appreciate any help here and answer on any questions. Thank you.
The device ID was likely updated in the drivers so the name changed, how GPU performance will not changing, your GPU will not magically become faster or slower.
We can probably recover the name with older driver reinstallation, but if i was you i would just ignore it and use your system.
