How to reduce GPU memory usage #13

Hello, I am trying to rebuild the Barn scene using the train.sh script, but an OOM error occurs every time it runs to around 20K. I am using a NVIDIA 4080 graphics card with 16GB of video memory. How can I reduce the usage of video memory so that my machine can also run GSDF?

Maybe reduce the resolution of hash grid in 'xyz_encoding_config' but it will lead to degraded quality.
