Any suggestions for reducing CUDA memory?

I'm using a 4090 to run your code on scannetpp, and encountered cuda oom at around 25000 iter. I have already tried to reduce the resolution of hash grid in 'xyz_encoding_config' as mentioned in another issue, but the situation still occurs. Any other advice?

When reconstruct DTU scan65, I met similar question(Especially every 5000 rounds, it seems to densey). Do you have any sugessition?

May I ask if you have solved this problem? I ran 22,000 rounds on DTU and encountered OOM as well. I have changed many parameters but it hasn't been resolved.
