Our running theory is that at “Prefer Maximum Performance” it is keeping the voltage and other factors so high that it is actually hitting the power limit wall or TDP wall, and thus causing GPU Boost to throttle back the clock speed a bit. This caused a little loss in performance. However, when we switched to “Prefer Maximum Performance” the clock speed dropped half-way through the game down to 1905MHz. It seems that on the GeForce RTX 2080 SUPER “Optimal Power” and “Adaptive” power have the exact same result. We tested the GPU Clock frequency on both video cards in all three power modes. The RTX 2060 SUPER did fluctuate a few degrees total, but it wasn’t a major difference. There also weren’t any major differences in GPU Temperature. It seems there are no big differences no matter the power mode when playing games at full tilt. This was also confirmed with the GPUz Power Consumption board power number. ![]() None of the power modes saved power or made the GPU consume more power while gaming. The power savings of both Optimal and Adaptive are worth it.Īt full-load though, playing a game we noticed no differences in the peak total system Wattage. Turning on “Prefer Maximum Performance” will make your Idle Wattage skyrocket. Quite simply, “Optimal Power” and “Adaptive” provide the best Idle Wattage power. In our testing, we found that the power modes do directly affect total system Idle Wattage. Power and Wattage are very important, you want the maximum performance, but you also want the most efficient way to get there. In addition, we looked at Power and Wattage, GPU Temperature and GPU Frequency to see if there are any hidden differences beyond gaming. We compared gaming performance in each power mode. In this review today we tackled that question head-on with real-world practical testing. Under the Power Management Mode, you are presented with the default option “Optimal Power” but you also have “Adaptive” and “Prefer Maximum Performance.”Ī common question that comes up is if you should change that setting to get better gaming performance. NVIDIA offers three power mode settings under its driver control panel. If you require further assistance, you should contact NVIDIA Support here. Note: The above instructions may change depending on version and unique graphics card. To further improve performance, you can also change the settings below:.In the "Specify the settings for this program:" section, click Power management mode and select Prefer maximum performance and confirm.Note: Depending on your GPU, this option might not be available.If possible, in the "Select the preferred graphics processor for this program" section, open the drop-down menu and select High-performance NVIDIA processor and confirm.Select the executable file for the game ( Fallout.exe).This will most likely be C:\Program Files (x86)\Steam\steamapps\common\Fallout 4\Fallout4. From the pop-up window, navigate to the folder where Fallout 4 is installed.Under this tab, select Fallout 4 under "Select a program to customize" option and click the Add button.In the Control Panel, select Manage 3D settings, then click on the Program Settings tab.Right-click on your desktop and select NVIDIA Control Panel.You can improve your NVIDIA GPU performance by following the instructions below: ![]()
