At the beginning of the year Canonical announced a Steam Snap package for Ubuntu ARM64 that leverages the FEX emulator for running x86/x86_64 games on ARM64. After months of testing and improvements, they now consider their Steam Snap for ARM64 to be stable.

Just in time considering this week's NVIDIA RTX Spark announcement , Canonical announced their Steam Snap for ARM64 is being treated now as stable. The platforms where so far they have found the Steam Snap on ARM64 to be working great includes the NVIDIA DGX Spark and other GB10 devices like the Dell Pro Max GB10 , Qualcomm Snapdragon X laptops, and the Radxa Orion O6/O6N.

Canonical will continue to maintain an "Edge" Snap version for their experimental work on Steam for ARM64 while now there is the stable version after going through the edge and candidate channels.

More details on the Steam Snap for ARM64 on Ubuntu being considered stable can be found via this Ubuntu Discourse thread by Canonical engineer Mitchell Augustin who specializes in NVIDIA DGX on Ubuntu.
