Does running Buff eat up memory and lead to poor FPS in Valorant?

Hey. I definitely understand the feeling of wanting to make use of the 144hz. As a general rule of thumb, so long as your PC is able to run the game, Buff can run in the background with no interference in performance or cause you any drop in frame rate. 4GB of RAM does meet the minimum system requirements for both Valorant and Buff, but if you are really looking to maximize performance, maybe lower the quality settings in game?
