![]() ![]() At TheFPSReview that is the mode, we will use for all of our evaluations. Optimal Power and Prefer Maximum Performance is all you need, and the latter being there for just legacy purposes.įor reviewers of computer hardware, benchmarkers, hobbyists and gamers we suggest leaving the Power Management Mode on the default “Optimal Power”. In our opinion, NVIDIA should cut down the options back to just two toggles. They both have the same power and performance. With Optimal Power we don’t really see the need for the Adaptive setting, they both almost do the same thing. It can actually cause your clock speeds to drop slightly, affecting performance. Unless you are having trouble getting your video card to run at the intended clock speeds, don’t enable this power mode. It seems “Prefer Maximum Performance” might even hurt your performance on certain video cards in certain games. This seems to provide the best Idle power savings and gaming performance. Based on our findings we recommend to keep the driver at its default setting of “Optimal Power”. While there are slight variances here and there, for the most part, they don’t make a big difference. Data points were taken in 3DMark, Power and Wattage in two different tests, and GPU Temperature. Included is a midrange video card and a high-end performance video card. We used built-in game benchmarks and real-world manual run-throughs in games. Included are performance taxing games, to lesser performance taxing games. APIs DX11, DX12, and Vulkan games were included, so all-important APIs are covered. When it comes down to it, we tested many different combinations of scenarios today. The experience was exactly the same between all three power modes on both video cards. What we did not see though was any particular power mode giving us an overwhelming or noticeable advantage to our gameplay experience. They could even be under the margin of error since we do run manual run-throughs in a couple of games. It wasn’t really consistent and we couldn’t find a real clear pattern.Īt the end of the day, the differences were tiny, and not noticeable in gameplay. ![]() Where one game benefited from one power mode, another game would be the opposite or the video cards themselves would flip flop. Which power mode was faster seemed to be random, and change every game. It seems some games were dead even, and others had a few FPS differences. This is really where the rubber meets the road, the real-world gaming results. It is enough of a difference though to say that you should just keep the setting on “Optimal” or “Adaptive.” Gaming Performance Therefore, it may only be something that can happen on certain levels of GPU performance. With the GeForce RTX 2060 SUPER this did not happen. It’s the best theory we have at the moment. 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. ![]()
