Create a baseline
Launch a minimal profile in a fresh world and observe performance before building a large structure.
Reduce avoidable load
General settings such as render distance, simulation distance and entity-heavy areas influence the headroom available to complex mod behavior.
Scale builds slowly
Prove a concept at smaller scale first, then increase complexity while comparing against the baseline.
Troubleshoot spikes methodically
If performance drops after an addon or dependency update, revert that change before altering unrelated graphics settings.
Practical takeaway
Keep the setup reversible. A separate profile, a world backup and a written record of versions make updates and troubleshooting far easier than reconstructing a working environment after several changes.
