From my side, i don't see reallly this rule.
For example in BFV :
if I set [email protected]
in V/F curve. I am at 22°c ambient.
Then the game starts at 38°C, then the clock is already down at 2160MHz.
Then, when temperature is roughly 41°C-42°C, then the clock goes down to 2145MHz.
At 47°C-48°C, the clock goes down at 2130MHz.
And I am sure at 50°C-52°C, it would go down at 2115MHz..
So you see, 2160MHz-2130Mz=30MHz=2x15MHz when GPU temperature goes from 38°C to 48°C...10°C....
So for me, it is more like -15MHz each 5°C more on the GPU...

as temps rise and stabilise at around 64C".
i don't know at which temperature the GPU is at when he starts playing BFV.
I don't know for other people...
