@Cbartlett the number one cause for gaming lag is poor WiFi link between the PS5 and your Sky hub. This is why keen gamers always use an Ethernet cable or powerline adapterscwhere thst is impractical. Beyond that if you game whiley multiple other members of your household are slso online perhaps streaming video then the hub can become overloaded and delays the data packets for your game. Sky hubs dont offer QOS which gaming routers have that can prioritise gaming traffic. Lastly at peak times you can get lag due to congestion in the connection to the gaming server this is not that common but can occur.
