I'm looking for trouble shooting tips on poor graphics performance on linux.

I have read through the FAQ's and done a basic search of the chimera list.

Observed:

Symptom:

Prohibitively slow rendering when just rotating a map, especially if a model is loaded as well. When using Isolde (and presumably anything with clipper) performance is more "normal" as only a small portion of the map is displayed.

System:

This is observed on Ubuntu distros (both 20.04 22.04) with their respective Chimerax packages, tested versions 1.6.1 and 1.9.

Nvidia drivers installed via the cuda toolkit (535.183.01   CUDA Version: 12.2 )

GPUs are either rtx 3090 or 4090s

Point of reference:

Performance is compared to my relatively very underpowered Windows thinkpad w/o discreet graphics.

Thanks for any pointers to resources!
