A few examples of existing specific/extreme saves I've profiled and found areas to optimize:
- During heavy combat with 120 + robots (particle slowdown)
- Having 5000+ beacons active at once (tick slowdown)
- Having 66,000+ robots on screen at the same time (Render slowdown)
- Opening a chest with 5000 slots (GUI slowdown)
- Having 50,000 + logistic containers and trying to render the logistic selection for all of them (Render slowdown)
If you're going to post a modded save please include the mods. The mods and save also need to run on the latest 0.15.
