The hub3 was known to have some latency problems, but nothing you could do about that. The hub4 may have some problems, but again, nothing you can change in the short term.
For gaming, it's typically far batter to use an Open Reach connection such as BT - the speeds are not as good but the latency is always less and more consistent, which is what you require for gaming. Some people use both - VM for downloading and OR for playing games. If you have a busy household, pushing the wife and kids onto the VM connection for YouTube/NetFlix etc is typically the best approach 🙂
