You should also make sure that the account running the sql server service has the local security policy right, Perform Volume Maintenance Tasks. This will allow for instant file initialization rather than waiting for the format to finish.
Remember this is for NON-TDE databases, SQL instances that use TDE cannot use instant initialization for the Tempdb as it is encrypted. As well any database on the instance that is using TDE cannot use Instant initialization as well.
