For what it's worth, it ran fine on my 2070 (8GB of VRAM), even with the GPU being used to render my desktop (Windows), which used another ~800MB of VRAM. I was running it under WSL, which also worked fine.

Note the level of investment that NVIDIA's software team has here: they have a separate WSL-Ubuntu installation method that takes care not to overwrite Windows drivers but installs the CUDA toolkit anyway. I expected this to be a niche, brittle process, but it was very well supported.
