Cheat Sheet

Laggy arena after copypasting empty space with paint tools
Made an arena maybe about 3000 x 2000 tiles, no tiles or torches in it, just living leaf walls and nothing else. Made it by copying a smaller arena (~500 x ~500) and pasting it several times. Now, even with Cheat Sheet disabled, and after a restart of TML and several times joining and leaving the world, it's sitting at around 50 FPS with huge frequent stutters, even when I'm on the other side of the world from my arena.

Prior to this, I had smooth 60.

Is this a common thing? Why does it happen? There should be fewer calculations happening, not more. Unless pasting walls+tiles with cheat sheet doesn't properly destroy things like light sources or liquids, even if they're no longer visible?

Made a similar sized arena in TEdit using a world backup. Same result: lots of lag. Going to try a few different things like not overwriting certain structures, or only posting air (no bg walls).

Yep, it's the walls alright. 100% consistent. As I start adding more walls to the world it gets laggier. Who would've thought walls of all things are a lag machine? I thought they would've been super low performance cost since 99% of the arena is out of render distance. But I guess the game is constantly doing checks on them :S

Didn't try other types of walls but judging from a reddit post with the same issue, any background wall is likely to cause it.

Don't add background walls to your giant arenas! So sad!
