Or you can use binary-packaged versions of CUDA compatible software, such as [https://github.com/edolstra/nix-warez/tree/master/blender blender-bin] for Blender.

Without ~~the~~ [[#Setting up CUDA Binary Cache|CUDA Cache]], any CUDA compatible package installed with <code>cudaSupport</code> will be compiled from source. This is because NixOS Foundation does not build (and therefore [https://cache.nixos.org/ cache.nixos.org] does not cache) CUDA packages.

For larger programs like Blender, that process can be very resource-intensive. If you know you are installing a large package and ~~cannot use the~~ cache, it is recommended to reduce the number of cores and/or jobs that the process will take, to prevent a crash from ~~memory~~ limits. This can be done with the <code>--max-jobs</code> / <code>-j</code> and <code>--cores</code> flags, for more details see the [https://github.com/NixOS/nix/blob/master/doc/manual/source/advanced-topics/cores-vs-jobs.md Tuning Cores & Jobs] page.

If you know you are installing a large package and are not using a cache, on older or weaker hardware it is recommended to reduce the number of cores and/or jobs that the process will take, to prevent a crash from resource limits.
