I see the nvidia inspector tool (not the profile tool), has the ability to play with clocks in various power states, but it last had an update in 2020 and doesnt seem to work properly on my card.įor now I am in prefer max performance with clocks capped to 1500mhz for the game, it will stutter in two tiny areas of the game, that need higher clocks, but otherwise works well albeit with excessive power/heat in menus. My questions are is this mode gone for good? I expect yes.Īlso has anyone find a way to adjust the ramp up aggression or maybe make it bottom out at 1500mhz clocks whilst in normal power mode? On adaptive mode, the clocks only go down to 800mhz in the menu's, and it will ramp up more aggressively keeping utilisation below 60%, I see no stutters at all in this mode as long as I don't go in and out the menu, if I go in the menu and give it time to drop to 800mhz, then exit the menu, there is a very short micro stutter a fraction of a second and then is smooth again. I assume so there is a smaller gap between base VDDC and peak VDDC. I haven't observed clear changes in the ramp up behaviour, just the higher base speed. it now sits at boost clocks 1710mhz which is considerably higher VDDC. In prefer max performance, the behaviour also changes, on the older drivers, it will sit at base 3d clocks, just over 1500mhz when at low load, on the new drivers that fix the stability issues on gigabyte etc. Its at its worse case when exiting the menu back into a demanding field area where the stutter might last a couple of seconds as the clocks go up, having to go from 420mhz up to 1900+. Both modes seem to be one extreme or the other, normal mode (optimal power) seems to only ramp up clocks when utilisation is very high about 90%, this leads to various stutters when I move to an area that has a sudden higher demand on the GPU as there is no headroom to absorb the extra power required and the ramp up is not very aggressive. So on Berseria, I have done play sessions in both modes. My FE card seems to have no issues using adaptive power on the original drivers. There doesn't seem much public info, but this more aggressive ramp up seemed to be what showed up stability issues in some 3080 sku's, so the mode is now gone. Officially the documentation states the only difference between adaptive and optimal power is that optimal power doesn't refresh data that's not on screen, however the observant amongst us would notice it behaves differently on how aggressive the clocks ramp up.
I have been doing testing using the following modes.Īdaptive Power (only possible on original ampere drivers). So I have been doing some play testing in Tales of Berseria, this is one of those old games that will let the GPU clocks go right down to 2d levels.
