Description

The game stutters significantly when placing or breaking blocks, which is quite frustrating as the game freezes for a split second every time a block is placed or broken. This happens with all blocks, including vanilla blocks and solid blocks. The world is quite new, and it’s been happening since I started it. It happens in all chunks, even ones where nothing has been built. alwaysSetupTerrainOffThread in forge.cfg is enabled as it is by default. OptiFine is not installed. I tried setting the mipmap level to 0, but that didn’t make a difference. 8.2 GB RAM is allocated, and memory usage isn’t going above 61%.

I used to have this issue back when playing Enigmatica 2 some years ago, but that time, it wasn’t a problem until I got a sizeable base with lots of tile entities ticking. This time, in E2E: Expert - Extended, it’s happening on a brand new world. Not sure what could be causing this, and I haven’t been able to find a fix.

Modpack version: 0.69.0 (latest)

To reproduce

Place or break blocks. Press alt + F3 to see the frame time graph.

Try to remove Entity Culling mod with it dependency.

Entity Culling isn’t installed (it’s not in E2E - Extended anymore, but its library mod RenderLib is, so you may want to remove that in the next release), but I did some testing and after a couple hours, figured out it was caused by Better Foliage, which I added to the pack, so my bad on that one! Went ahead and submitted an issue on its issue tracker, but it’s doubtful it’ll be fixed considering 1.12.2 is an old version, and it was also reported over three years ago but remains an issue.
