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!
