Today Gran Turismo Sport was unveiled by Sony Interactive Entertainment, but apparently what you're seeing today isn't close to the final product just yet.

During the reveal livestream that is currently being aired, it was mentioned that the game's development is only 50% comnplete. We also learned that the folks at Polyphony Digital are iterating very fast, and are pushing out new builds all the time.

For instance, the build that was available at the event yesterday night was an earlier build compared to the new one that is being aired today. "huge improvements" are being made.

That said, the game was already running at full 60 frames per second at today's event, with frame rate and performance that definitely looked nice and stable.

On top of that, we also learned that the game's professional difficulty is extremely challenging.

GT Sport will launch in Japan, Asia and North America on November 15th, in Europe on November 16th and in UK on November 18th, exclusively on PS4.
