In the above graph, we are looking at the GPU frequency on the GeForce RTX 2060 SUPER FE. Prefer Maximum Performance – 1914MHz GeForce RTX 2060 SUPER The average of the clock speeds turns out to be the following. We don’t exactly know why perhaps it is hitting the TDP wall faster? The Prefer Maximum Performance actually drops clock speed for some reason a ways in down to 1905MHz. That means the Optimal Power and the Adaptive option are actually maintaining a higher frequency at 1920MHz throughout the game. It starts off at 1920MHz like the others, but then half-way in it drops in frequency down to 1905MHz and stays consistent at 1905MHz the rest of the game. However, something a bit different happens with the Prefer Maximum Performance option. That means both Optimal Power and Adaptive consistently have a frequency that comes out to 1920MHz and it doesn’t change. In all power modes the clock speeds start at a high level and step down to their final resting spot, this is normal and it happens the same way at the same time in each power mode.Īt the 1920MHz mark, you see the blue line of the Adaptive option, what you don’t see is that underneath that line is the orange line for Optimal Power as well. GeForce RTX 2080 SUPERįrom the get-go these results are interesting. Where overlaps occur, you may only see one color. Optimal Power is in orange, Adaptive is in blue and Prefer Maximum Performance is in green. In the graphs below we are showing all three power modes compared on one graph for each video card separately. I think its a bug, as I have owned many previous gen cards and they never had this behaviour.īut curious if anyone else has noticed this, note its probably not going to be an issue in modern games which load up the gpu, also if people are not capping framerate.Let’s first start by looking at the real-world gaming GPU frequency between each power mode. game stutters when exiting menus as it has to get out of idle clocks, so I tried prefer maximum performance, and its going down to 2d clocks, and not only going down it seems to do it a lot, the game was a stutter fest. I noticed when playing fable anniversary if I use optimal performance its not that bad but it isnt perfect, e.g. So expected behaviour based on all my old nvidia gpu's, is that when this option is selected the gpu clock speed will never fall below base 3d speed (typically somewhere in the mid to high 1000mhz range.), the benefit of this option is for older games where the gpu is overpowered so it falls down to 2d clocks, but then this causes stutters as 2d clocks wont be enough to run game smoothly, so typically in these games the gpu can have a problem of looping between 2d and 3d clocks, which "prefer max performance" fixes. Seems this isnt working properly for me, unless its changed by design.
