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 Optimal power superseded the previous default, called “Adaptive”.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. So, it did have a big effect, at one point.By default, NVIDIA sets the power management mode of your GPU (be it in card or laptop form) to “Optimal power”. Forcing the highest maximum performance power mode would fix the issue and force all GPUs in an SLI configuration to run at their full-speed in games for the best SLI scaling.
In drivers of years past it was recommended that you set “Prefer Maximum Performance” if your SLI configuration was experiencing little to no performance gains.
This one is a bit of a legacy setting, it existed at a time when things like 2-way or 3-way or even 4-way SLI didn’t always accelerate each GPU at maximum potential. The big question is will it help us with gaming performance? This means higher Idle Wattage, and heat just sitting there doing nothing. Prefer Maximum Performance – This one does as it says, it maintains the card at its maximum performance state no matter what, even in Idle. It should strike a balance between using Optimal Power in Idle states, and maximum performance in heavy 3D loads automatically. It’s a big vague in specifics, but technically it can control voltage, GPU frequency, and memory frequency as well.

According to the NVIDIA Control Panel Adaptive allows the graphics driver to automatically determine the proper performance state based on GPU usage.
This is all about improving Idle power.Īdaptive Power – Adaptive Power is another option you can select, it use to be there before Optimal Power even existed and used to be the default setting a long time ago. In theory, this should reduce power without affecting performance.

Similar to the other options voltage, GPU clock speed and memory clock speed are controlled, as well as something else.īasically, when your PC is idle and the screen is not changing the GPU will not render new frames, instead it re-uses frames rendered in the framebuffer. After then, now Optimal Power is the default setting. Until then only two modes existed, Adaptive and Prefer Maximum Performance. Optimal Power – This option was introduced with the GeForce GTX 1080 in driver version 368.22 back in May of 2016.
