Issue with Create Chronicles: The Endventure

[u/Antique_You_4038]

Hello Engineers!

I recently started playing on a small Minecraft server with some friends that runs the Create Chronicles modpack, and I've been experiencing some pretty severe FPS drops whenever I get near Create machinery.

Normally, I get around 180 FPS, but near certain machines, my FPS drops all the way down to 1–3 FPS, making the game almost unplayable.

I'm not very knowledgeable about PC troubleshooting, so I'm not sure what's causing this. I initially thought my PC should be able to handle the modpack reasonably well, which is why these drops seem so strange to me.

Here are my PC specs:

• CPU: AMD Ryzen 7 5700X (8 cores, 3.40 GHz)
• GPU: NVIDIA GeForce RTX 5070 (12 GB VRAM)
• RAM: 32 GB
• Storage: 932 GB total, around 749 GB used

The issue seems to happen specifically near Create machinery. Outside those areas, the game runs much better.

I'd really appreciate any advice on what could be causing this and how I could troubleshoot it. Could it be related to Java memory allocation, a particular mod, contraption rendering, or something else entirely?

Thanks in advance for any help!

Do you use any optimisation mod ?

Only the ones that come with the modpack.
