I launched Carla on my laptop that has a 4GB Nvidia 1050Ti GPU. The graphics took several minutes to come up and even then the output looked weirdly glary. I checked
nvidia-smi
and it seemed that the process was not running on the GPU. I am running Fedora 35 and I have deliberately configured my system to use the builtin Intel GPU by default.In previous versions of Fedora I was using
optirun
to launch applications that required a GPU for rendering or other CUDA support. While my system shows an option to run installed applications using a dedicated GPU, I was not sure how to that for an application being launched from the command line. After researching a bit on how it works under the hood, I found out that there is a utility on newer Linux releases by the nameswitcherooctl
. I was able to useswitcherooctl list
to get the ID for the Nvidia GPU and then usedswitcherooctl launch -g GPU_ID ./CarlaUE4.sh
to run Carla on the GPU. It's considerably faster and the graphics look natural.Before vs After
