Compared to 26.1-rc-3 and 26.1, 26.1-rc-3 has no FPS drop when looking at baby mobs, however 26.1 has severe FPS drops, when looking at the same baby mob on both, 26.1 drops FPS by ~20-30, while on 26.1-rc-3, there is no FPS drop

Can you provide a video of this in action? It could help diagnose what you are experiencing.

Attached is a video (apologies for the slightly low framerate, this is due to recording) but notice the FPS, it drops by a ton looking at a baby mob

Does this still occur in the latest snapshot?

As of 26.2 Snapshot 3 on both Graphics APIs (Vulkan and OGL) It still does, but at lower rates than before

Could you also conduct the same experiment but using an adult mob instead (or even a different mob that doesn’t have a baby variant), and compare the results?

looks like its fixed as of 26.2 snapshot 8, the FPS drop between baby and adult zombie for example is practically the same
