f.lux using max gpu clock when idle
its a really waste of power voltage.
It's not supposed to do that.
I discovered the same thing today after using f.lux on this machine for YEARS..
When f.lux is running, my graphics card will not dynamically adjust its frequencies in relation to workload at all, it just sits there with the clocks maxed out.
As the OP pointed out, this is a huge waste of resources when it comes to the electricity bill, but also in terms of additional wear and tear on graphics cards.
