Ever since Minecraft 1.21.5 update, I’ve been experiencing a reduction in FPS. On the previous version, 1.21.4, I got FPS around 116-117 FPS with the 120 FPS cap. With 1.21.5 I get around 90-109 FPS with the same 120 FPS cap. The game has a lot of stutter now.
Issue happens on native Minecraft launcher and Lunar Client as well.
Environment
I'm running Minecraft 1.21.5 on a 14 inch MacBook Pro (M4 Pro) on macOS Sequoia 15.4

What is the max FPS of your monitor?
For some reason, in my experience, the FPS will never reach the max, it will only approach the max.
Are you playing singleplayer, or is the server on a different machine?
Try this:
Add 10 and round down to the nearest 10 and use that as your max FPS.
It fixed frame drops for me.
(If your monitor is max 60FPS, set the max FPS in Minecraft to 70)
(If your monitor’s max framerate is 70FPS, set the max FPS to 80)
My Mac has a 120hz display and I’m playing on Singe player world. I’ll try your suggestion though, thank you!
Ah I missed those, my bad. This was my first post on this system.
I have the same problem. To be fair is way worse with shaders and iris (never experienced problems in 1.21.5) but I think mojang is not related to shaders and iris problems
