![]() But knowing how this system works, I'm not sure that will yield the result that you wanted and might just force the OS to use the IGP for everything.Īlthough, the context of your question suggests its not really Optimus you are having issues with, but rather nVidia's automatic performance scaling when on battery power.įrom nVidia's customer support page: Setting "Power management mode" from Adaptive to Maximum PerformanceĪlso go into Windows' own power settings and create or alter the High Performance profile to have Maximum performance on everything, especially CPU. There are some newer laptops in which I've observed a BIOS option that allows one to disable the Optimus feature. See this SuperUser post/answer: Brian's answer I want to turn off this technology so my graphics card performance won't get reduced on battery power. I think I didn't make myself clear, so here's an edit: ![]() Kind of sucks.Īnyways, just to let you know, on AC power, BF4's performance would be at 40-60+ FPS, and on battery power, the performance would be at 20-35+ FPS. You might think I could've just removed the battery, charge the laptop itself and play the game but no, my laptop comes with a non-removable battery pack. ![]() My question is, how can I turn off this useless technology? I purchased the graphics card so I could enjoy games with higher FPS.īy the way, my GPU has been over clocked and playing graphically-intensive games such as Battlefield 4 has a relatively high FPS, when on AC power. The Optimus technology by NVIDIA is said to automatically control performance of graphics card, like increasing performance when the laptop is on AC power, and reduce performance on battery battery.
