A mate has a problem with your client, he is using an i5 4670k, not overclocked. When he start the Client, his CPU Usage up to 10-15 %, when he join my invite or click somewhere in the apps, it can go up to 20% I’m using an i7-6700k and my cpu usage of the apps is 2-3%. Is it normal for his CPU ? Thank you for your help
Can you check with him on the idle CPU usage for the app? As in, start the app and don’t interact with it. It should stay at 0% for both of you. However, some CPU usage when you are interacting with it (like loading a lobby) is normal and is not an issue.
