It takes a bit of trial and error to find the right setting that doesn’t cause your laptop to freeze or crash, but the benefits are well worth the effort. This is a handy technique for notebook owners who want to undervolt their GPU, reducing its heat and power consumption. While mobile GPUs have become very efficient in the last two years, every little bit counts.įinally, for those who don’t mind getting their hands dirty, it’s possible to change the power curve of modern NVIDIA GPUs using MSI Afterburner. If you’re on a notebook, you’ll definitely want to make sure “Optimal power”, or at least “Adaptive” is selected in the global settings.

You can then use “Prefer maximum performance” for only those titles. For demanding games that don’t play well with Optimal Power or Adaptive, find (or create) the required profile in the “Program Settings” tab of the “Manage 3D settings” page. The NVIDIA Control Panel allows you to configure profiles for games on a case-by-case basis. Unfortunately, this will increase the “idle” heat and power draw of your GPU, even when you’re not doing anything. Now, it’s tempting to hit up the driver’s global settings and set the power management mode to the aforementioned value and never think about it again. As the name suggests, this setting will run your card at its maximum clocks all the time. Newer NVIDIA cards feature several more options, such as “NVIDIA driver-controlled” and “Prefer consistent performance”, but the only other choice you need to worry about is “Prefer maximum performance”. However, Optimal Power adds another feature - it’ll stop the GPU rendering a new frame if nothing has changed on screen and instead reuse what’s already in the framebuffer. Both options will modulate the core and memory clock speeds and voltage of your GPU, increasing them during times of load and decreasing them when demand is low. Optimal power superseded the previous default, called “Adaptive”.

This setting was introduced into the company’s video drivers with the GTX 1080, specifically version 368.22 release in May 2016. default, NVIDIA sets the power management mode of your GPU (be it in card or laptop form) to “Optimal power”.

Doing exactly what the Nvidia wiki page proposed.

When I disable the card entirely (in NixOs), I get a draw of ~2W, but I would love if the offload mode could yield the same results. To be honest, I do not know if this is what should be expected, but it seems too high. I previously used Arch Linux, where I used Optimus-Manager to manually turn it off. When referencing the wiki page on nvidia, it seems that the card should power completely off when not in use.

Hey! I’m trying to get nvidia prime offload working on a Dell XPS 15" 7590.
