This is more of a question fro GPU Z forums. The tool is good not not perfect.
I have an Hp Envy 15 3090 Notebookk PC and it comes with the AMD Radeon 7690m. In device manager and in GPU Z however the card shows as 'AMD Radeon 6600m and 6700m Series'. The intel and amd drivers I have were downloaded automatically when I installed windows 8.1 so I haven't downloaded any drivers from their respective page. Everything works fine, switchable graphics works great however I wonder if my graphics card is being slowed down because windows think I have the 6600m and 6700m series. So is my graphics card not working at its full potential because of this? If it isn't then how do I fix it? Thanks in advance.
