Massive FPS drop going from Minecraft 1.21.1 to 1.21.11

On 1.21.1 I was getting 200+ fps with my usual mods. Same world, same settings on 1.21.11 and I'm down to about 80. Did something change, or do my mods just need updating?

Did your video settings carry over? New versions sometimes reset render distance or push simulation distance back up. F3 shows your real fps and which GPU is in use, check that before blaming mods.

check your mods first. lots of people jump versions and end up without sodium, or with an old build that silently didn't load. also make sure java is still running on the dedicated gpu and not the integrated one.
