How to show your FPS in Apex Legends
Be aware that this is for PC users and not console!
The setting is going to be in your Origin account, not in the game itself.
Step 1: Open Origin
Step 2: On the top-menu, click on “Origin” and select “Application Settings”
Step 3: Select the “Origin In-Game” tab
Step 4: Under the option “During Gameplay”, select where you want the FPS counter to display
During your next game opened with the Origin launcher, you’ll have the FPS displayed on the screen in the position you chose.
