(Quick update all works well in the depths up until you jump on one of the skeleton horses that's when stuff starts slowing down again)
Review update, about depths broken. Ryujinx user. Upon deleting the @stop commands and just leaving the last one and enabling fsr and disabling lod as other users stated below. I was able to finally run the game smoothly but also by bumping down graphics from 3x to 2x.. on hyrules surface on 3x everything is fine but below in depths experienced slowdown and prior to tweaking the code in the visual fix mod I couldn't get it to run smoothly at all constant slow mo. Anyway look forward to future updates and such.
