Seeing how many FPS your game runs at can be very useful for a quick paced game like Valorant. Luckily for is it's very easy to find out how many FPS you have while playing, and it can be done easily from within the game itself.
To see how many FPS you have in Valorant, head to the main menu and click on Settings in the top-left corner. Click on the "Video" tab, then the "Client" tab and select how you want the FPS to be displayed from the "Client FPS" option (at the very top).
This allows you to play the game and see exactly how smoothly the game runs. If you ever want to turn it off again, simply head back to the same menu and turn it off from there.
