Yoga C940 14" slow performance after BIOS update
I stupidly installed the latest BIOS update (AUCN59WW) without doing research and now I'm seeing a significant performance hit. It looks like specifically I'm seeing large spikes of GPU usage which then bogs everything down and causes me to drop frames. I haven't made any recent changes to the Intel GPU drivers.
Is there any way to revert to a previous BIOS version? Is there anything else that can be done? Lenovo support is being less than helpful.
