lag spikes
PhanaticD opened this issue ยท 5 comments
I kept getting annoying lag spikes in my game ~200ms spikes while rendering, so I used jprofiler in exception mode and ended up at WorldRender.setupTerrain and after looking in the code for that class and noticing mojang records info in debug mode turned that on and ended up with this:

example spike, usually occurs every few seconds: https://i.gyazo.com/7b0ace314438a994ef1e79c4ad3c7a7b.png
System Information
Do you encounter these spikes with vanilla as well or just with Sodium?
Could you upload a crash report triggered by holding F3+C?
Do the spikes coincide with a drop in memory usage as shown in the top right of the F3 screen? If they do, try reducing your RAM allocation to 2G or 4G.
A better place to debug this would be the #mod-support channel in the Caffeine Discord: https://jellysquid.me/discord
they happen with just fabric loader with and without mods, with vanilla or optifine I do not notice any lag spikes
crash: https://paste.gg/p/PhanaticD/84d18a0f84f14366a23a24d34c4d82e6
java settings were originally 2g I changed that a bunch, default, ZGC, higher, lower, it had no effect, and the spikes do not line up with gc changes
If the spikes occur with no mods, it's not a Sodium issue. I or someone else can help you to try and diagnose the issue in the Discord if you'd like, but this issue tracker isn't the place.
