GPU Tweak III Adds GPU Level Sense for ROG Astral Series GPUs

[Silent_Scone]

Level Sense is a GPU Tweak III feature that utilises the card’s onboard orientation sensors (gyro/accelerometer IMU) to detect when the GPU is no longer level (i.e., sag/tilt) and then warns you, allowing you to correct the mount/support.

Supported GPUs

ROG Matrix Platinum GeForce RTX™ 5090

ROG Astral LC GeForce RTX™ 5090

ROG Astral GeForce RTX™ 5090

ROG Astral GeForce RTX™ 5090 OC

ROG Astral GeForce RTX™ 5090 BTF 

* Astral 5080/5090D/White SKUs also supported

 

What you need

1. GPU Tweak III v2.0.8.5 (or newer) 

2. A supported ROG 5090 Matrix, or Astral GPU.

3. If GPU Tweak prompts for an MCU update when enabling Level Sense, that’s expected on some Astral setups (GPU Tweak may request an “MCU_update…” package).

Set it up

1. Open GPU Tweak III → click “Level Sense”.

2. Calibrate if needed

   • If the GPU is already installed and reading sensibly, you can skip calibration.

   • If prompted (or readings look off), click Calibration to set a baseline.

3. Set your Threshold and Save

   • Default is 0.30°.

   • Lower = more sensitive (alerts sooner).

If the threshold is exceeded, you will get a pop-up notification in the system tray and the Level Sense section will alert you to off-angle installation. Ensure a sufficient threshold is set; we recommend 0.30.
