FSX. According to PMDG CEO Rob Randazzo, the team has finished with work on the SP1 update for the 777-200LR/F and are focusing on quality control. No one can argue with that. Along with many numerous unmentioned new features the service pack will deliver, the one of notable mention is the advanced weather radar implementation that is currently being created in partnership between PMDG and HiFi Technologies. Now I really could try and get into it here, but it's best for you to head over to the official announcement for more information. And who said weather radar was not possible in FSX? Thanks to ADX AJ pongress for the tipoff!
