Valve has posted an update on Steam about the status of Steam Machine reservations and waitlists - orders are currently being fulfilled on an ongoing basis.

Two smaller technical updates came along with it: FSR 4.1 is now available on Proton Experimental for supported titles, and Valve released the CAD file for the Steam Machine’s external housing.

Quick Steam Machine updates:

• FSR4.1 is now available on Proton Experimental for titles supporting FSR upgrade.
• The CAD file for Steam Machine external geometry is available for download.

We’re fulfilling orders on a daily basis, sending out emails to reservation holders with the option to purchase in the order in which they landed on the list post-randomization. We expect everyone in the reservation queue will have the option to purchase by the end of this year.

With each reservation queue and corresponding waitlist being per-product, per-region, they can move at different speeds based on demand. For some products in some regions, we’ve reached the end of the reservation queue and have started inviting folks from the waitlist.

Importantly, no one on the waitlist is leapfrogging over anyone currently holding a reservation; we’re only dipping into waitlists if and when we reach the end of the reservation queue for that product and region.

For everyone receiving a purchase email: You must complete your purchase within 72 hours or we will move to the next person in line.
