Minecraft used to run at 60 fps no problem when it was in windowed. I am using a mac with macOS with Intel Iris Pro 1536 MB Graphics. My Processor is 2.5 GHz Quad-Core Intel Core i7. As of 20w22a the program lags even when I'm just standing there not doing anything. (See screenshot).
Additionally, this is a special type of low fps. I don't get frame drops, I just consistently get low frames which makes my game run in the past.
