When gaming using the trackpad, I noticed it would often ignore my inputs. This is due to the palm rejection and can be disabled:
Go to "Start > Settings > Bluetooth & devices > Touchpad" and expand the item with the index finger icon(it is below the cursor speed item). A bunch of new options show up, and to the right there's a drop-down list of different sensitivities for palm check.

I noticed when my laptop would wake from sleep, it would often take a few notificable seconds to reconnect to wifi. Fix this by disabling wifi power saving and disable "auto change from sleep to hibernation"
I noticed my bluetooth mouse and keyboard would sometimes have trouble reconnection. Disable bluetooth power saving fixed it.
By default, Windows 11 uses a Microsoft account and stores all files on Desktop/Downloads/Documents/Photos in Onedrive instead of locally. You can change this setting to revert back to local storage.
