i have problem with lags. I have good net nad perfect ping and transfer from 4 years. Few days ago situation changed. Today speed test is 45/10 Mbps.
Could you know what i must to fix that problem?
Since there had been no response so far, I would give it a try.
If the problem only occurs when you play SWAT 4, try restarting your modem/router before you play. Make sure you are not downloading stuff and no other devices (phone, TV, tablet, PC, etc.) are connected to the router and drawing massive bandwidth.
Also, if the speed tests are still consistently bad, you might want to call your ISP's customer support to see if they can help you.
