Is it possible to get equal performance from a laptop when it's on battery (vs when it's on AC)? I'm running an object recognition application on my webcam feed, but the FPS drops 2-3 times on battery power, which is unacceptable. I'm using the high performance option under power options, but is it possible to keep the laptop from throttling my GPU?
Disable power saving at both the OS and the Hardware levels.
Currently we are assuming you are using Windows (ver?) since you didn't specify. But despite selecting High Performance in the Power Menu go into the advanced options and just turn off all the power saving features for the OS. Look to see if the GPU manufacturer has some additional settings. Latly, go into the BIOS of the laptop and turn off any power saving features there.
