ChimeraX not communicating with GPU

[TANY0517@…]

Dear Developers,

Hope this email finds you well.

I have encounter an issue regarding the GPU driver usage for chimeraX.

The issue is that the model and density movement is very choppy at step size 1, with a box size of 400.

Here are some information on the software that I am using.

Downloaded Software:
Ubuntu 22.04 (Linux)
ucsf-chimerax_1.9ubuntu22.04_amd64.deb<https://www.cgl.ucsf.edu/chimerax/cgi-bin/secure/chimerax-get.py?file=1.9/ubuntu-22.04/ucsf-chimerax_1.9ubuntu22.04_amd64.deb>

This is my current nvidia driver and cuda version:

NVIDIA-SMI 560.35.05              Driver Version: 560.35.05      CUDA Version: 12.6

It came to my attention that it is not utilising GPU upon running "graphics driver" on chimeraX, which outputs:

graphics driver

OpenGL version: 4.5 (Core Profile) Mesa 23.2.1-1ubuntu3.1~22.04.3
OpenGL renderer: llvmpipe (LLVM 15.0.7, 256 bits)
OpenGL vendor: Mesa

additionally, it is not showing up under nvidia-smi when I am running the program.

Is there any solutions to this issue?

Thank you in advance.

Regards,
Eddie
