Computer Memory Usage Lag

Hi,

Running tasks in the background and failure to meet the system requirements to play these games are some of the possible reasons why your PC experiences a high memory usage.

For us to identify what's causing the issue, we'll be needing additional information:

• What specific games are you playing when the issue is happening? Is it online or offline?
• Were you able to play this games without any issues before?
• Can you send us a screenshot of the processes running on your Task Manager while you are playing the game?

We look forward to your response.
