Incredibly high CPU usage (~1 fps) on 1.20.1

[ColossalRenders]

Using world generated with reTerraForged at world height 1024 causes fps drop to around one frame per second, specifically on mountains. When on flatter ground I get maybe 30 fps. Note that this is with all Distant Horizons features and shaders turned off (but still installed). When weather is not set to rain, I can run the game perfectly fine at 90 (capped) fps.

intel 13700f all cores maxed

Full mod list when the issue appeared. I have since removed everything except DH, Sodium, Iris, RTF, WWEE, Immersive Weathering, and dependencies, with no improvement:

On vanilla worlds it's slightly better. If I turn off all DH rendering and distant generation it runs fine. (CPU usage at ~20%) If I turn on DH rendering and distant generation but set the weather to clear, it runs fine (CPU usage at ~90%, 70-90 (capped) fps). It's only with rain and distant generation that my frames drop to around 30.

Another issue I ran into with these mods: wind wisp consistently crashes game upon joining world.

Can you provide the log file instead of text? I can't do much from this.

[ColossalRenders]

For the crash or for the frame rate issue? I can do both but be warned for the latter DH spams my logs with multi line errors every tick or frame (it just does that if I have Iris installed); the log file is multiple GB and won't even open in notepad.

I will be able to provide the log files later today hopefully.

In this instance I had all my mods loaded but the issue is still there when I'm only using the minimal setup I described in the original post (Cloth Config, Cristellib, DH, Wyther's EE, Fabric API, Fabric Kotlin, fzzy config, immersivewind 0.7, iris, particle core, particle rain, RTF, sodium)

i need to see the 11 more lines from that error

I think I solved it but I can only tell so much from what you gave me. The fix will be in the next update
