Microsoft will be detailing and showing off its Xbox Series S and Xbox Series X-optimized titles later this month.

Following the early Xbox Series X impressions, various media outlets and YouTubers have shown off backwards compatible titles running on Microsoft’s upcoming next-gen console. These titles, however, are running on the console right out of the box without any additional optimizations.
