[Feature Request] Enable power limit slider for mobile gpu like driver 528.24

Hi,

i noticed that with Nvidia driver 528.24 you have a slider for power limit for mobile gpu. If you disable "NVIDIA Platform Controller and Framework" device in device manager and put the power % slider all the way up you force nvidia dynamic boost to the max, so the gpu will use max power whathever the cpu wattage.

However NVIDIA remove it from driver 531.18, there is a way to implemenmt a fix to enable that again with NVCleaninstall in successive drivers? That is really helpful for laptop performance.

Example: my 3060 mobile throttle to 80w if the cpu is consuming more than 42w. With that fix and that specific driver, i am able to run that at 95w whatever wattage the cpu is pulling.

Ty all

Interesting .. Can you check if you get the same results using MSI Afterburner by adjusting the power limit? i.e. does the NVIDIA slider really just change the classic power limit, or something else. You could also use the nvidia-smi command line tool for the same task

That slider, in laptop with NVIDIA dynamic boost capable GPU, work like this:

- at 100% it will limit the TDP of the card at the non dynamic boost TDP (in my case 80w)
- you can go over 100% with that slider to allow the gpu use the dynamic boost TDP.

I forgot to mention in the first message that the slider, with that specific driver, is available only MSI afterbuner.

Disabling NVIDIA controller the gpu will not be limited by the cpu wattage usage. The max TDP set in the gpu bios will not change, but that 15w tdp boost (in some laptop is 25w) is a good amount of performance increase (for me a 10/15% fps increase in cyberpunk), so if you will be able to implement a fix in NVCleaninstall to enable the slider for newer driver, every nvidia laptop user will be soo grateful, and I will be the first one



Ok, i have understand what is the nvidia.smi command line and how to play with that.

I have 2 different windows partition, one with driver 528.24 and the other one with driver 536.40.

I have play a little bit with these commands line:

- nvidia-smi -q -d POWER
- nvidia-smi -pl 95



Here are the stock results of "nvidia-smi -q -d POWER" with 528.24:

Fuck Nvidia. This was goos also to lower the temps if i need to.

What do you think about it? Can it be fixed? There are some files we can swap to have the power settings enabled again?

Apologies for the bump on this, but has something been figured out? I have done this on my laptop, with a 3070ti - the performance difference between 115/125w and 150 is substantial. Thanks

Mine used to go up to 80w 3050ti but with the new 531.xx drivers I can no longer boost to 80w only goes to 60w :( power slider in afterburner is greyed out. If there is some update to fixing that would be helpful.

Sorry to bump this too but I noticed this behaviour since some months and I got not fix except to install the full drivers from nvidia with all bloat and telemetry, someone found any fix?

I can confirm this, this looks more like a bug from NVcleaninstall on Laptops. Installing the newest drivers with NVcleaninstall give me only 115W of power on normal or extreme, and using Nvidia Normal Installer it give me the normal output: 138 on normal mode and 150 on extreme. Gpu is 3070 TI

I can confirm that the Power Limit slider becomes locked-out after driver updates from both NvCleanstall AND going through the OEM installed GeForce Experience. First time it happened to me, I was testing an ASUS G17 that I ended up returning. So this time I decided that maybe it had something to do with needing to use only OEM laptop display drivers from MSI's support page. Either way, once the update was complete, the slider was locked. I wish I had tested actually setting various power limits, but I hadn't done it yet. Now I'm thinking I should DDU and re-install those OEM drivers and cross my fingers that MSI releases another update eventually.
