There could be several reasons why you are experiencing lag in your games. Here are a few things you can try to fix the issue:
Check for background processes: Make sure that there are no other programs or processes running in the background that may be hogging system resources. Close any unnecessary programs, especially those that use a lot of resources, like web browsers or video editing software.
Update your graphics card drivers: Make sure that you have the latest drivers installed for your graphics card. You can usually download the latest drivers from the manufacturer's website.
Lower game graphics settings: Lowering your game graphics settings can help to reduce the strain on your GPU and CPU, which can lead to improved performance.
Monitor your system temperatures: Overheating can cause your system to slow down and lag. Use a software like HWMonitor to monitor your system temperatures, and make sure they are within the normal range.
Check your network connection: If you are experiencing lag in online games, make sure that your network connection is stable and that you are not experiencing any packet loss.
Check for malware: Malware can slow down your system and cause lag in your games. Run a malware scan with your anti-virus software to check for any potential threats.
Upgrade your hardware: If none of the above solutions work, you may need to consider upgrading your hardware. A newer, more powerful graphics card, more RAM, or a faster processor can all help to improve gaming performance.
I hope these suggestions help you to improve your gaming experience. If the issue persists, you may want to seek additional help from a professional technician.
