you should disable windows firewall. go into control panel and type in firewall in the search bar and open the settings and disable it. also make sure that when you're playing this game that nothing's going on in the background. do a speedtest from speedtest.net and make sure that your ping is at least below 80. If it's not then you need to shut something that's running in the background like a download or a firewall or a messenger application,etc.
