In recent laptops, even before series 20 Turing GPU, PRIME does a good job, since running everything from nvidia won't overheat nor run fans near 100%. It will only dissipate heat or raise the fans when you really need it. Overall, the computer will run faster on nvidia. But in the only laptop I actually possess PRIME is not usable because of hardware limitations on powersaving while running nvidia. This graphics card seems to be unable to underclock. It will even impact CPU performance: the dedicated GPU dissipates enough heat to get the CPU near it's throttling temperature, even when the graphics are close to idle. That means the CPU is always close to underclock. As soon as I can I'll build and try to fix any issues I encounter with bumblebee. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
