In fact, the situation that QQ takes up too much CPU resources may be related to the settings of your QQ software. Modifying the settings of QQ can solve the problem.
First, reduce the frequent pop-up messages of qq groups, block the automatic pop-up chat messages of some infrequently used qq groups, regularly clean up the junk messages in QQ groups, and delete the unused groups, otherwise the residual chat records will accumulate too much.
Second: Turn off "Show Custom Avatars", the display of various avatars of friends may take up a lot of resources!
Thirdly, it is also very important to select "Recent Contacts" and click "Clear Recent Contacts List". Then select Interface Manager-Component Management-Folder Options-Remove the checkmark in front of the nearest contact, so that he will not display the nearest contact. After many tests, it is found that displaying the nearest contact is the key factor leading to the card, and it is also the key step of this solution!
Fourth: Turn on "Show only online users", which is unnecessary, because sometimes it is not convenient for you to find invisible friends.
Fifth: Turn off "Show User Prompts". If this function is not very important to you, you can cancel this function!
Sixth: Enter the qq system settings, turn off the "sound settings" and block all friends' ringtones.
Seventh: qq interface manager-panel settings are cancelled, and qq search component management is also cancelled.
Eighth: Go into the directory of your qq number in Program FilesTencent and see if the chat database MsgEx.db is very large. I have been to1100mm. Do you think it is possible to stop the card? Unable to view the history chat with friends. Consider backing up chat records and cleaning them up. Or delete the whole program file Tencent, your qq directory, and then log in to qq again to start over, but remember to back up your chat history, and it is best to copy the whole qq directory before deleting it.
