“Lag” covers two different problems. Network lag is when the game reacts late or players teleport because data takes too long to arrive. Frame lag is when your PC cannot render the game smoothly. Fixing the right one starts with telling them apart.
Network lag or low FPS?
Most online games can display network statistics: ping (latency), packet loss and sometimes jitter. Turn them on alongside an FPS counter.
- High ping (over about 80 to 100 ms in fast games) or spikes: network delay.
- Packet loss: data lost on the way, causing rubber-banding and shots that do not register.
- Low or unstable FPS with normal ping: a performance problem on your PC, not the connection.
Use a wired connection
Wi-Fi is the most common source of jitter and packet loss. An Ethernet cable to the router removes it almost entirely. If a cable is impossible, use the 5 GHz or 6 GHz band, keep the PC close to the router, or consider powerline adapters or a mesh system with a wired backhaul.
Free up your connection
Downloads, cloud backups, 4K streaming on another device or a game update in the background can saturate the line, especially the upload. Pause them while playing. Our guide to getting your full bandwidth on a PC covers the Windows side in more detail. If your router supports QoS or a gaming mode, use it to prioritise your PC. Restarting the router clears many temporary slowdowns.
Choose the right server
Ping depends mostly on physical distance. Make sure the game is set to the region closest to you rather than “auto”, which sometimes picks a distant server. Playing with friends abroad will always add latency for someone.
Check the line itself
Run a ping test to a reliable server, or use the game’s built-in diagnostics, at different times of day. If packet loss appears even on a cable, the problem may be your router, the modem or your provider’s network. Tools like WinMTR show where along the route packets are lost, which is useful evidence when contacting your provider.
PC-side settings
Update your network adapter driver from the motherboard or adapter maker. Disable VPNs while gaming unless you need one, as they add a hop. Some network “gaming” utilities bundled with motherboards cause more problems than they solve; if lag started after installing one, try uninstalling it.
When it is not on your side
Sometimes the game’s servers are overloaded or having issues. Check the game’s status page or social media accounts before spending an evening changing settings. If everyone in the match is lagging, the problem is almost certainly not your connection.
