Hi, I’m able to play this game with medium-high settings at stable 40fps but battery life is not great then I realized that I can limit TDP so I did it with 11w. Still 40fps but much better battery life. My question is why FPS is not changed with TDP limit and increased my battery life?
To add to this, a lot of times chips use more voltage than is actually necessary to ensure stability across the silicon lottery, but more often than not they can run with much lower voltages and still perform fine with certain workloads. This could be what’s happening here as well.
Another thing is that the OS CPU governor could just be a bit overzealous by default and clocking it at frequency that’s way higher than it needs to be to run a certain game. On my desktop Arch machine with a Ryzen 3900x, a lot of times I see a CPU core boosting to max frequency even though the CPU load for that core is only 50%. Reducing TDP helps to bring that frequency back down.
