Lag when loading chunks (with and without shaders)
So in vanilla everything is hunky dory and all is performing well with no frame drops, but whenever I use Iris it has trouble loading chunks and lags. I've tried it with Iris alone and with performance mods like sodium (all listed below) and it still has trouble. Depending on how much stuff there is in the chunk the worse the lag becomes.
I looked it up and saw some github post about deferred chunk rendering so I went and turned that on (and raised the threads from 0 to 3) and the lag got WORSE 😠so I am not super sure what to do now, help would be appreciated!

What launcher are you using
forgot to add that, Prism
never had this issue before but I suppose prism could be causing it now for some reason?
going to try with the vanilla launcher really quick
nope! still laggy with the vanilla launcher
gave it double the ram (from 4 to 8 gigs) and nothing changed
this sounds counter intuitive, but lower ram is sometimes better
4 i all you should need under normal circumstance
maybe 8 with a reasonably high render distance
or mods
yeah i set it back to 4 because it didn't need all that anyways
minecraft used to run fine with iris installed, then i wiped my computer and boom now it craps out
only difference in my pc in terms of hardware since then is i installed an nvme ssd
Try downloading the starlight mod?

idk if it works on 1.20.1, probably does
Starlight most likely won’t help
