[Tom Goddard]

You mentioned on the ChimeraX mailing list that this machine has 4 Nvidia RTX Pro 4500 (32 GB each) but this bug report shows ChimeraX is not using the Nvidia driver and instead is using Mesa software rendering.

OpenGL version: 4.5 (Core Profile) Mesa 23.1.4
OpenGL renderer: llvmpipe (LLVM 17.0.6, 256 bits)
OpenGL vendor: Mesa

If you were using the nvidia graphics driver it would not run out of memory.

It also appears you are using remote display since I see environment variable "DISPLAY=:2". OpenGL often does not work correctly via remote display. If you do get it to work with compatible graphics drivers on both the client and server then it is the graphics on the display computer is what will be used. Probably your display computer does not have 4 high-end GPUs. We don't recommend or offer support for remote display as described here

​https://www.cgl.ucsf.edu/chimerax/system_requirements.html

To easily see if ChimeraX is using the Nvidia graphics driver use ChimeraX command "graphics driver" and it will report the OpenGL driver to the Log panel.
