I’m on a MacBook (M2) and learned that Chrome must be fully killed before launching it with flags. I was following Lesson 46 from threejs-journey.com, and these are the steps that finally made the FPS counter appear.
Step 1. Made sure to kill all Chrome processes:
killall "Google Chrome" 2>/dev/null

Step 2. Launch Chrome with the correct flags (including the FPS counter):

open -na "Google Chrome" --args \
  --disable-gpu-vsync \
  --disable-frame-rate-limit \
  --show-fps-counter
