The Xbox Series X and S have a handy "Optimised for Xbox Series X/S games" filter.
This is something spotted by Xbox console preview users last month, and was just tweeted by Microsoft's Larry Hryb.
You can access the filter from the Games list.
It's a nice option for new Xbox Series X and S owners who want to try out optimised games as soon as their consoles arrive from 10th November.
Microsoft added a similar feature for the launch of the Xbox One X.
