![]() ![]() With the latest nvidia drivers (344.75) and previous ones, wont let me change the Power management mode setting to Prefer Maximum Performance. So, it did have a big effect, at one point. Power management mode keeps reverting back to Adaptive after applying Prefer Maxiumum Performance. 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. While in this mode, the GPU is kept at higher frequencies. Reducing System Latency: Enable Max Frame Rate and set your power management mode to Prefer maximum performance to reduce latency. The big question is will it help us with gaming performance? If either of these modes are enabled at the same time as Max Frame Rate, the NVIDIA Control Panel will cap the framerate to the lowest of the limits. 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. Are you a PC gamer looking to optimize your Nvidia graphics card for the best possible performance Then you've likely seen the Nvidia Control Panel options for Optimal Power and Prefer Maximum Performance and may be wondering which one to choose. You can also configure a second GPU by incrementing the GPU and fan number. 'Nvidia Power Management Mode - Optimal Power VS Maximum Performance. nvidia-settings -a ' gpu:0/GPUFanControlState1' -a ' fan:0/GPUTargetFanSpeed n '. Replace n with the fan speed percentage you want to set. ![]() Optimal Power – This option was introduced with the GeForce GTX 1080 in driver version 368.22 back in May of 2016. Place the following line in your xinitrc file to adjust the fan when you launch Xorg. ![]()
