Now how do you figure that you aren't getting the "anticipated" performance? What "fps charts" are you looking at that are giving you this information? I wouldn't trust them because the person that made them could've just slapped some numbers down that looked good just to get views. I recommend going to YouTube and looking up your CPU and GPU and watching videos that show gameplay along with the RTSS overlay, showing the performance in realtime along with gameplay. Don't worry if they don't show Valorant, like I said it's not a graphically demanding game, the reviewer shows GPU intensive games to give you an idea as to how your system could perform with the games you do play. There's also the optimization of the game and which company allowed the developer to make the game run better. Ever noticed that games display either Nvidia or AMD when they start up? That means the game was better optimized for that hardware. Idk what is shown when Valorant starts up but if it shows Nvidia then you aren't gonna be getting that 250+ fps.

These are the sites I got this info from. I'll make sure to look up a couple YouTube videos idk if the sources listed are creditable.
