Hello O9B0666, this was interesting. I decided to run it again and i got this. You can also see that there was no overclock before. This era of Gpus from AMD is very wierd ,imo.
I am also interested to know what you mean by, "my graphics card driver is not approved". Could this be the reason for the similar score?
