　　[Original story] Gran Turismo 7 Update 1.06 is currently being deployed for both PlayStation 5 and PlayStation 4.

　　The update is being rolled out alongside scheduled server maintenance, with servers planned to be back up shortly (March 10, 2022, 07:00 - 09:00 UTC, March 9, 2022, 23:00 - 01:00 PST). No official release notes have been shared just yet, but we do know that this update weighs in at roughly 906MB, and it will likely include various bug fixes alongside additional optimizations. We’ll update this post as soon as the official release notes for this update become available.

　　Gran Turismo 7 is available globally now for PS5 and PS4. Down below we've included a part of Chris Wray's (updated) review of the latest Gran Turismo installment.

　　Having a tighter feel is just what you can say about almost every aspect of Gran Turismo 7. Gran Turismo may brand itself as "the real driving simulator", but nobody has ever believed that. It is a simcade racer, but every iteration comes closer to perfecting that line between simulation and arcade. I don't doubt for a second that Gran Turismo Sport, and its more narrow focus, has helped to drive the improvements of racing here. The physics are top-notch, each car feels unique in the way it handles the bends and straights, and this applies doubly so when you pop into the garage and make some adjustments.

　　From repeated aquaplaning on a rainy day, as you watch the water settle into dips and corners, to feeling the rumble as you edge just a little too close to the inside, there's something genuinely special about the racing here. I want to say I've tried it with a wheel, but I haven't - I expect to have a wheel with me in a matter of a few days, so more on that shortly. Still, from the racing I've done, it's just fantastic. I can't honestly say I've had a better on-track experience from a traditional racing game.
