Massive FPS drop when looking towards LP setup
Opened this issue ยท 4 comments
Hello, one of the players on my server has a large LP setup, however it seems to be causing some massive FPS lag (server TPS seems unaffected). Standing at my base looking/walking away from his LP setup I get 100+ FPS, however as soon as I turn around and face the direction of his base (which is several hundred blocks away and just outside of my render distance), my FPS tanks to 20-25. Turning my back on his base brings my FPS back up to 100+. The other two people playing on the server have both reported the same. I was looking through the logs trying to find anything clues as to what was causing the massive drop, and came across this:

You can turn off player messages in the CCL config file.

Which leads me to believe it may be LP related.

I can provide a full modlist if needed. Also am happy to provide any other additional information if needed.
After further testing and profiling with LagGoggles, it appears to specifically be caused by the players autocrafting setup. Here are some screenshots of the setup causing the lag:
It's probably the crafting signs. The renderer on those is pretty inefficient. See #1315
