If you experience this, select "Auto-select" or the default selection. Your selection may cause some programs to not run correctly or may result in shorter battery life. Programs and videos that launch on external displays that are driven by the NVIDIA GPU will always use the NVIDIA GPU rather than the integrated graphics processor, regardless of the "preferred graphics processor" selection. Specify the graphics processor to use when you launch the program. Specify the graphics processor to use through the Manage 3D Settings "Preferred graphics processor" setting. When programs are run on displays connected to the integrated graphics, you can customize this selection in two ways: When you run a program, the NVIDIA driver automatically selects the appropriate graphics processor to use for the best performance - either the integrated graphics processor or the high-performance NVIDIA GPU. How do I specify which graphics processor my program uses? Note: Your PC manufacturer may provide a custom Windows power plan that prevents programs from using the high-performance NVIDIA processor. If there are no programs or displays using the NVIDIA GPU, then the window indicates that your PC is in power saving mode. When you click the NVIDIA GPU Activity icon in the notification area of the Windows taskbar, the window shows which programs and displays are using the NVIDIA GPU. The technology optimizes the balance between power savings and performance, and is available only with Windows 7 and later. NVIDIA ® power-saving GPU technology (NVIDIA ® Optimus™ technology for notebooks) automatically turns the high-performance NVIDIA GPU on to accelerate programs or displays. They're just annoying like that.Using NVIDIA's Power-Saving GPU Technology I was working on a Dell laptop for work yesterday where the unit refused to accept a previous generation Dell power adapter (older 90W adapter on a newer 65W unit) even though the voltage was identical. Any time I have worked with a Dell, I have just used a Dell power adapter because it was easier, even if there were cheaper third-party options available. It won't help the situation in Ubuntu, but it might at least give you the performance you are looking for when in Windows.ĭell is also known for making the use of non-proprietary power adapters a pain in the ass. Switching to "High performance" worked, though battery life is abysmal. No matter what he set via drivers/third-party utilities, for some reason the Windows option overrode his settings. My friend was experiencing the same issue in Windows with his Dell Precision laptop (NVS 3000 series GPU I believe) and the culprit ended up being the "Dell" power plan in Power Options. ![]() In Windows in particular, are you running the Dell installation of the OS or did you do a fresh install from your own media? The laptop is Optimus capable, though turning it on had no effect other than letting me run things on my integrated GPU. On Windows, there's no powermizer settings (though there is a "power management mode" set to prefer maximum performance), but I did add the keys to disable them them as described here. I originally thought it was just on Linux only (see my askubuntu question here), but I did check Windows and GPU-Z, and it does the same thing when running heavy 3D applications. It also affects the CPU, but I can set ignore_ppc in linux or throttleclock in windows to get around that. Also, if I plug in a third party charger that's > the required 230W, it still stays in this state: 135-648 MHz core-memory out of 705-3600 MHz On battery, I'd like to be able to use the full GPU (or at least more than the minimum). My laptop's NVIDIA GPU refuses to leave the lowest power state unless the official dell M6800 charger is plugged in.
