#NVIDIA MX550 Power LImit Issue

I have an NVIDIA MX550, and any even slightly demanding game (for it) which I play, like Dark Souls Remastered, runs fine for like the first 5 minutes, then the power limit of the GPU drops to 1 Watt, making the game unplayable. I have tried everything, BIOS tinkering, Coolbits, NVIDIA Panel tinkering, nothing seems to work. I think this is a OEM issue.

Also attached to this post is the screenshot of nvidia-smi command before and after... as is evident, the previous power limit is 30W, and after just a little bit of time, it is dropping to 1W
I have no idea what is happening... please help... almost all games are unplayable except for extreme indie games like Undertale/Celeste.

OS - Ubuntu 24.04 LTS
DE - Hyprland (JaKooLit's dotfiles)

Systems specs are listed in the next message.

sudo nvidia-smi -pl 30 is not working as the MX550 does not support manual power limit adjustment.

#

And no, getting a better GPU is not an option, i'll be getting a 4060 laptop next year so I'm stuck with this for now

Although Nvidia has made major strides in Linux driver development especially with their drivers being open sourced since 2024, the Nvidia Linux Desktop driver is still lackluster and not as stable as Intel or AMD Radeon drivers on Linux, with the Nvidia Linux drivers do not support latest graphical or system implementations from major Linux distributions. The following are the current persistent issues of Nvidia drivers on Linux:

Poor VKD3D & RT performance, due to a combination of drivers and optimizations needed for NVIDIA cards, with high performance penalty compared to Windows in DX12.

The following features are still work in progress and may be broken: Hardware Video Decoding / Encoding support, Adaptive Sync/G-Sync, NVIDIA Optimus (If you are running a laptop, please set your laptop to use the dGPU using the mux switch), Power Suspend, Explicit Sync on Wayland

The "NVIDIA Control Panel" on Linux lacks a lot of features. The NVIDIA app is unavailable on Linux.

If you do intend to use Nvidia drivers for Linux, please do the following:

Ensure that you are downloading the drivers from your OS repository (APT/YUM) rather than from the Nvidia website unless your OS does not have a pre-made Nvidia driver package.
Please read the changelogs and documentation for each OS/Distro on Nvidia driver installations and workarounds.

Get yourself a Radeon laptop if you are planning to use Linux

this issue happened to me on windows too

Have you checked the temps and benchmarks of your laptop?

HWINFO has two modes, Summary and Sensors. Normally, when asked, you'll want to use the Sensors-only mode to get the information that may be needed (e.g. temperatures, power usage, clock speeds.)

When opening HWINFO, make sure to tick "Sensors-only" so that it does not open the summary display first. Then click Start.

On some hardware, HWINFO may ask if you want to monitor them or not, as there may be some potential conflicts if they were monitored. Usually these aren't important enough to matter if it's being monitored or not.

Once HWINFO's sensor status window open, look for the relevant sections and screenshot them. If you're unsure, screenshot the entire thing. This window is scrollable, so you'll need to scroll and take multiple screenshots.

If you know what you're doing, these are the items you'll probably need (names may vary; below are samples from Intel CPUs; some items may not exist for your particular system):

  • Core VIDs
  • CPU Package Temperature
  • Core Thermal Throttling
  • Package/Ring Thermal Throttling
  • CPU Package Power
  • PL1 Power Limit (Static)
  • PL2 Power Limit (Static)
  • MOS
  • VR VOUT
  • +12V
  • Vcore
  • CPU Fan
  • Pump Fan
  • GPU Temperature
  • GPU Hot-spot
  • GPU Core Clock
  • GPU Power
  • GPU +12V
  • GPU Fan
  • GPU Performance Limit Reasons
  • Windows Hardware Errors (WHEA)

the XE ones

#

thats not a gpu capability issue

fallow basin
#

have you even done that?

split niche
#

as for benchmarks

#

ivd done those, but stressful benchmarks drop the power limit

#

normal benchmarks run well and good

#

one sec

#

lemme pull results

Please perform a 3Dmark benchmark and HWINFO sensor window
