How to Fix Valorant UnrealCEFSubProcess.exe on PC

Is Valorant UnrealCEFSubProcess.exe consuming a lot of resources on your PC?

Valorant is a fairly easy game to run on most PCs. In fact, the game only requires an Intel i5-4150 CPU and a GeForce GT730 graphics card to run at 60 FPS. 

This is why some Valorant fans can’t help but wonder why the game is lagging on their very capable machines. 

One of the culprits is the high CPU usage of resources like the UnrealCEFSubProcess.exe.
