If true, NetConnection::Tick can be run in parallel. This is designed as a runtime disable flag to be used alongside config changes. To enable parallel tick, it also requires the NetDriver config bCanUseParallelNetConnectionTick=true and ReplicationSystemConfig bAllowParallelTasks=true.
Usage
net.iris.AllowParallelNetTick [value]
Set via the console (~) or in DefaultEngine.ini / DefaultGame.ini.
