Twilight Forest version: 3.3.202

Going anywhere near the aurora palace causes everything to lag like crazy unless the game is paused. I noticed its due to the blocks changing color. perhaps just add a config option to turn the visual effects off?

is it client or server lag? The color changing should not contribute to lag any more than say a bunch of water, it's just an animated texture.

Running singleplayer. anytime Id go near the palace unless the game was paused chunks wouldent even load.I assumed it would somehow be the textures due to them stopping when paused

I'd say that would be worldgen lag. I also don't think the Aurora Palace had been touched since the dev builds, and it may be unoptimised.

It is incredibly unlikely that Aurora Blocks can cause this as they function the same way water has with a animated texture.

Feel free to reopen this issue if this issue still persists in the latest version, a debug profile is needed to find the cause then.

Linking this to #733 (comment) i'm sure this is the real cause and to finally solve the mystery of this issue.

I have the same problem but even pressing esc not for I noticed that the animation itself that for some reason I get lag at 1 fps and I go back to normal maybe it’s errors being generated by something, I didn’t go to another castle to test if it changes but I think it is the block, I was flying seeing each direction of the block whenever I looked at it lagava or when I am not really loaded chunk. If anyone knows how to solve it please help I wanted to play every twilight like the giants but I can't because of that
