I can't quite believe this got a 9/10 'official' review. If you want to see your house from the air then go online and load up Google Earth in 30s. If you want to wait 10 hours for a game to install, then wait 6 minutes every time you want to load a game or change location then this is the game for you! Seeing your own home is a great marketing gimmick, but this just inst ready for release. Performance is so bad - and not just when you're flying over a complex urban area (which could be forgiven), but all of it - load screens, installation, etc.
I run an overclocked 1060-6gb, with an overclocked i5-6600k, and two high end SSDs, but the game just doesn't look exceptional on 1080p with toned down settings. And on 4k with high settings, yes it looks good, but the frame rates are in the single digits over urban areas - so not really usable.
I'm sure there's a good game hiding here, but dont bother to install it yet - wait for at least 2 or 3 major performance patches first.
