Request for Support with RTX 4090 Mobile Dynamic Boost Issue on Alienware m18 R2

Dear Dell Support Team,

I am reaching out to discuss a significant issue I've encountered with my Alienware m18 R2 laptop, which is equipped with an Intel Core i9 14900HX processor and an NVIDIA RTX 4090 Mobile graphics card.

My concern revolves around the Dynamic Boost feature on the RTX 4090 Mobile, which is designed to enhance gaming performance by allowing the GPU to exceed its standard 120W power consumption and reach up to 175W. While this feature operates seamlessly on Windows, providing stable and expected performance levels, I have encountered substantial difficulties when using Linux as my operating system.

Under Linux, Dynamic Boost is not activated by default, resulting in the GPU's power consumption being capped at 120W. Despite following NVIDIA's documentation and enabling the `nvidia-powerd.service`, the GPU fails to consistently exceed the 120W limit or reach the potential 175W, leading to highly fluctuating power consumption and, consequently, unstable performance.

I have documented my experience and the steps I've taken to address this issue in a complaint posted on the NVIDIA GeForce Forums. You can find the details of my complaint here: https://forums.developer.nvidia.com/t/dynamic-boost-issues-with-rtx-4090-mobile-on-linux/283605.

Given the complexity of this issue, which appears to involve both hardware capabilities and software support, I am reaching out to you at Dell for assistance. Could you please advise if there is a known solution or workaround that could stabilize the Dynamic Boost functionality under Linux? Additionally, I am interested in any steps Dell might be taking in collaboration with NVIDIA to address this compatibility and performance concern for Linux users.

Your support in this matter is crucial for me to fully utilize the capabilities of my Alienware laptop. I appreciate any guidance or solutions you can provide.

Thank you for your attention and support.

Best regards,

Vincent.
