High CPU Usage from System Interrupts and Anti-Malware Service Executable

[ignoramuswrestler]

Hello,
I am using a Dell laptop with an i3 CPU, and whenever I play Valorant or any other game, my laptop starts to lag very badly after 1-2 hours due to high CPU usage by several services: System, System Interrupts, and Anti-Malware Service Executable. I manually changed the trigger for the Anti-Malware Service scheduled scan using Task Scheduler to scan the system once a week, so it no longer interrupts while gaming. However, the System Interrupt service consistently consumes CPU only while gaming. How can I stop this?

Thank you for your help!
